Update chat/matrix-synapse to 1.25

Synapse 1.25.0 (2021-01-13)
===========================

Ending Support for Python 3.5 and Postgres 9.5
----------------------------------------------

With this release, the Synapse team is announcing a formal deprecation policy \ 
for our platform dependencies, like Python and PostgreSQL:

All future releases of Synapse will follow the upstream end-of-life schedules.

Which means:

* This is the last release which guarantees support for Python 3.5.
* We will end support for PostgreSQL 9.5 early next month.
* We will end support for Python 3.6 and PostgreSQL 9.6 near the end of the year.

Crucially, this means __we will not produce .deb packages for Debian 9 (Stretch) \ 
or Ubuntu 16.04 (Xenial)__ beyond the transition period described below.

The website https://endoflife.date/ has convenient summaries of the support \ 
schedules for projects like [Python](https://endoflife.date/python) and \ 
[PostgreSQL](https://endoflife.date/postgresql).

If you are unable to upgrade your environment to a supported version of Python \ 
or Postgres, we encourage you to consider using the [Synapse Docker \ 
images](./INSTALL.md#docker-images-and-ansible-playbooks) instead.

### Transition Period

We will make a good faith attempt to avoid breaking compatibility in all \ 
releases through the end of March 2021. However, critical security \ 
vulnerabilities in dependencies or other unanticipated circumstances may arise \ 
which necessitate breaking compatibility earlier.

We intend to continue producing .deb packages for Debian 9 (Stretch) and Ubuntu \ 
16.04 (Xenial) through the transition period.

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

The old [Purge Room \ 
API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api/purge_room.md)
and [Shutdown Room \ 
API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api/shutdown_room.md)
are deprecated and will be removed in a future release. They will be replaced by the
[Delete Room \ 
API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api/rooms.md#delete-room-api).

`POST /_synapse/admin/v1/rooms/<room_id>/delete` replaces `POST \ 
/_synapse/admin/v1/purge_room` and
`POST /_synapse/admin/v1/shutdown_room/<room_id>`.
