chat/matrix-synapse: Update to 1.98.0

Synapse 1.98.0 (2023-12-12)

Synapse 1.98.0 will be the last Synapse release in 2023; the regular
release cadence will resume in January 2024.

Synapse will soon be forked by Element under an AGPLv3.0 licence (with CLA, for
proprietary dual licensing). You can read more about this here:

    https://matrix.org/blog/2023/11/06/future-of-synapse-dendrite/
    https://element.io/blog/element-to-adopt-agplv3/

The Matrix.org Foundation copy of the project will be archived. Any changes needed
by server administrators will be communicated via our usual announcements channels,
but we are striving to make this as seamless as possible.

Features

  - Synapse now declares support for Matrix v1.7, v1.8, and
    v1.9. (#16707)

  - Restore tracking of requests and monthly active users when
