Synapse 1.58.1 (2022-05-05)

This patch release includes a fix to the Debian packages, installing the
systemd and cache_memory extra package groups, which were incorrectly
omitted in v1.58.0. This primarily prevented Synapse from starting
when the systemd.journal.JournalHandler log handler was configured.
See #12631 for further information.

Otherwise, no significant changes since 1.58.0.
