chat/matrix-synapse: Update to 1.57.0

Upstream NEWS, less bugfixes and minor improvements:

* Synapse 1.57.0 (2022-04-19)

  This version includes a change to the way transaction IDs are managed
  for application services. If your deployment uses a dedicated worker
  for application service traffic, it must be stopped when the database
  is upgraded (which normally happens when the main process is
  upgraded), to ensure the change is made safely without any risk of
  reusing transaction IDs.

* Synapse 1.57.0rc1 (2022-04-12)
