2.2.3 is the first container image tag that is available as a multi-arch image
with support for linux/amd64, linux/arm64/v8 (arm64) and linux/arm/v7 (arm32),
so self-building is no longer necessary on all these platforms.

Upgrade Mautrix/Facebook (0.3.2 -> 0.3.3)

Not tested but shouldn't break something

Update honoroit (v0.9.3 -> v0.9.4)

feat(mx-puppet-slack): add support for OAuth client ID/secret

The OAuth credentials method seems to be the only viable way to
configure the mx-puppet-bridge now. Legacy tokens can no longer be
created, and the other methods (xoxs and xoxc tokens) come with warnings
about them being against Slack's terms of service.

(untested change, but unlikely to cause breakage)

Synapse v1.51.0 requires to be built with BuildKit since
https://github.com/matrix-org/synapse/pull/11691

The `docker_image` Ansible module does not support BuildKit
(https://github.com/ansible-collections/community.general/issues/514),
so we had to switch to a `docker build` call.

Update Synapse from 1.50.1 to 1.50.2

Fixes a issue with room version 1.

Merging has to wait until ARM images are built ofc.
