chat/matrix-synapse: Update to 1.62.0

Upstream relevant changes:

  Port the spam-checker API callbacks to a new, richer API. This is
  part of an ongoing change to let spam-checker modules inform users
  of the reason their event or operation is rejected. (#12857, #13047)

  Allow server admins to customise the response of the
  /.well-known/matrix/client endpoint. (#13035)

  Add metrics measuring the CPU and DB time spent in state
  resolution. (#13036)

  Speed up fetching of device list changes in /sync and
  /keys/changes. (#13045, #13098)

  Improve URL previews for sites which only provide Twitter Card
  metadata, e.g. LWN.net. (#13056)

  Remove the unspecced DELETE /directory/list/room/{roomId} endpoint,
  which hid rooms from the public room directory. Instead, PUT to the
  same URL with a visibility of "private". (#13123)
