Update Synapse v1.59.0 -> v.1.59.1

This new version should be buildable on arm64.

See: https://github.com/matrix-org/matrix-hookshot/releases/tag/1.7.0

There's still no prebuild arm64 image, so we continue relying on
self-building there.

Update Postgres (CVE-2022-1552 + last 9.x update)

Update mautrix-whatsapp v0.3.1 -> v0.4.0

Upgrade Heisenbridge (1.12.0 -> 1.13.0)

Related to https://gitlab.com/mx-puppet/discord/mx-puppet-discord/-/issues/117

Looks like the bridge is too quick to start and fails to initialize
itself by connecting to Synapse. It's mostly observed after a system
reboot, because Synapse (and everything else) is slower to start.

Once mx-puppet-discord fails to initialize itself, a "No relay found"
error will be observed any time you try to relay a Matrix message to
Discord. Relaying messages in the other direction (Discord to Matrix)
also fails.

With this workaround (longer delay on mx-puppet-discord startup), I
observe mx-puppet-discord working well, even after a full reboot.
Of course, a proper fix is preferable, instead of delaying by a magic
number of seconds.
