chat/matrix-synapse: Update dependencies

I missed that some dependencies now are required in a newer version.

Log message:
Update chat/matrix-synapse to 1.21.2

Synapse 1.21.2 (2020-10-15)
===========================

Debian packages and Docker images have been rebuilt using the latest versions of \ 
dependency libraries, including authlib 0.15.1. Please see bugfixes below.

Security advisory
-----------------

* HTML pages served via Synapse were vulnerable to cross-site scripting (XSS)
  attacks. All server administrators are encouraged to upgrade.
  ([\#8444](https://github.com/matrix-org/synapse/pull/8444))
  ([CVE-2020-26891](https://cve.mitre.org/cgi-bin/cvename.c … 2020-26891))

  This fix was originally included in v1.21.0 but was missing a security advisory.

  This was reported by [Denis Kasak](https://github.com/dkasak).

Bugfixes
--------

- Fix rare bug where sending an event would fail due to a racey assertion. \ 
([\#8530](https://github.com/matrix-org/synapse/issues/8530))
- An updated version of the authlib dependency is included in the Docker and \ 
Debian images to fix an issue using OpenID Connect. See \ 
[\#8534](https://github.com/matrix-org/synapse/issues/8534) for details.

Synapse 1.21.1 (2020-10-13)
===========================

This release fixes a regression in v1.21.0 that prevented debian packages from \ 
being built.
It is otherwise identical to v1.21.0.

Synapse 1.21.0 (2020-10-12)
===========================

No significant changes since v1.21.0rc3.

As [noted in
v1.20.0](https://github.com/matrix-org/synapse/b … 2020-09-22),
a future release will drop support for accessing Synapse's
[Admin API](https://github.com/matrix-org/synapse/t … /admin_api) \ 
under the
`/_matrix/client/*` endpoint prefixes. At that point, the Admin API will only
be accessible under `/_synapse/admin`.

Bugfixes

    Fix a bug introduced in v1.20.0 which caused the synapse_port_db script to \ 
fail. (#8386)

Log message:
Update chat/matrix-synapse to 1.20.0

Synapse 1.20.0 (2020-09-22)
===========================

No significant changes since v1.20.0rc5.

Removal warning
---------------

Historically, the [Synapse Admin
API](https://github.com/matrix-org/synapse/tree/master/docs) has been
accessible under the `/_matrix/client/api/v1/admin`,
`/_matrix/client/unstable/admin`, `/_matrix/client/r0/admin` and
`/_synapse/admin` prefixes. In a future release, we will be dropping support
for accessing Synapse's Admin API using the `/_matrix/client/*` prefixes. This
makes it easier for homeserver admins to lock down external access to the Admin
API endpoints.

Synapse 1.20.0rc5 (2020-09-18)
==============================

In addition to the below, Synapse 1.20.0rc5 also includes the bug fix that was \ 
included in 1.19.3.

Features
--------

- Add flags to the `/versions` endpoint for whether new rooms default to using \ 
E2EE. ([\#8343](https://github.com/matrix-org/synapse/issues/8343))

Bugfixes
--------

- Fix rate limiting of federation `/send` requests. \ 
([\#8342](https://github.com/matrix-org/synapse/issues/8342))
- Fix a longstanding bug where back pagination over federation could get stuck \ 
if it failed to handle a received event. \ 
([\#8349](https://github.com/matrix-org/synapse/issues/8349))

Internal Changes
----------------

- Blacklist [MSC2753](https://github.com/matrix-org/matrix-doc/pull/2753) \ 
SyTests until it is implemented. \ 
([\#8285](https://github.com/matrix-org/synapse/issues/8285))

Synapse 1.20.0rc4 (2020-09-16)
==============================

Synapse 1.20.0rc4 is identical to 1.20.0rc3, with the addition of the security \ 
fix that was included in 1.19.2.

Synapse 1.20.0rc3 (2020-09-11)
==============================

Bugfixes
--------

invalid JSON data is encountered. \ 
([\#8291](https://github.com/matrix-org/synapse/issues/8291))

Synapse 1.20.0rc2 (2020-09-09)
==============================

Bugfixes
--------

notifications to misbehave following the implementation of unread counts. \ 
([\#8280](https://github.com/matrix-org/synapse/issues/8280))

Synapse 1.20.0rc1 (2020-09-08)
==============================

Removal warning
---------------

Some older clients used a [disallowed \ 
character](https://matrix.org/docs/spec/client_ser … questtoken) \ 
(`:`) in the `client_secret` parameter of various endpoints. The incorrect \ 
behaviour was allowed for backwards compatibility, but is now being removed from \ 
Synapse as most users have updated their client. Further context can be found at \ 
[\#6766](https://github.com/matrix-org/synapse/issues/6766).
