Update synapse 1.95.0 -> 1.95.1

auto-detection logic will run. Passing it explicitly spares the Jitsi
role some work.

Hopefully, this makes it clearer that it's not just "public rooms"
that will now be exposed,
but rather "public rooms which are also published to the room directory".

This brings the values up-to-date as of the latest indexing run done
today. Due to a bug, the previous values were somewhat off.
The new numbers are different and actually demonstrate that the situation is
much worse than initially imagined.

Update apache example for support discovery

Update ajbura/cinny Docker tag to v3

Update MSC1929 integration

It seems like with the default versioning detection strategy (`docker`),
the version is detected up to the hyphen:

> Renovate tries to follow the most common conventions that are used to tag Docker images.
> In particular, Renovate treats the text after the first hyphen as a type of platform/compatibility indicator.

Perhaps with `semver` would be more appropriate for this image.
