community build: stop injecting sbt-dotty

The sbt-dotty plugin was deprecated with the release of sbt 1.5.0,
and removed from the dotty build in b477c42

However it was still being injected into the community build, as many
projects therein had not been updated to a recent sbt, or were using a
(possibly outdated) version of sbt-dotty either directly or indirectly
via some other plugin.

This commit discontinues that practice, since sbt 1.6.x no longer plays
nice with sbt-dotty (see the linked ticket #14391).

Many of the community build projects are already updated upstream to
use sbt 1.5.x or 1.6.x without sbt-dotty; those are updated to their
upstream versions in this PR as appropriate.

A handful of community build projects are either unmaintained or do not
offer Scala 3 support upstream, or their inclusion in the community build
was part of some special effort. Those projects, listed below, have had
their dotty-staging forks updated to use sbt 1.6.2 and drop sbt-dotty.
