deps: update various sbt plugins (#17462)

This updates the following:

- sbt-sonatype from 3.9.10 -> 3.9.20
- sbt-pgp (now under com.github.sbt) 2.0.0 -> 2.2.1
- ~sbt-pack from 0.13 -> 0.17~
- sbt-buildinfo from 0.9.0 -> 0.11.0
- sbt-mima-plugin from 1.1.0 -> 1.1.2

Note there are a couple others that are still outdated (sbt-scalajs,
sbt-jmh), but they may require some more work, so I've purposefully left
them out of here.

EDIT: I remeoved the sbt-pack update as there are some breaking changes
in there that I'll need to address. I'll do that in a different pr.
