Publish to Maven central using sbt-ci-release and groupId `com.github.sbt`

The artifacts of sbt-multi-jvm are only available on repo.scala-sbt.org currently which just had a multiple hours outage.

@eed3si9n if you add credentials I will add the pull request and then we should cut a new release.

• Tell scala steward about migration Migrate sbt-multi-jvm scala-steward-org/scala-steward#3266
• Make scala steward come visit: Add sbt/sbt-multi-jvm VirtusLab/scala-steward-repos#330

Fixes #58

@mkurz Added creds, and also granted Admin rights to @sbt/play-team.

@eed3si9n For some reasong PGP_SECRET and PGP_PASSPHRASE are missing: https://github.com/sbt/sbt-multi-jvm/settings/secrets/actions which makes the release fail: https://github.com/sbt/sbt-multi-jvm/actions/runs/7168117212/job/19515581734
Can you add them? Thanks!

Ping @eed3si9n thanks!

I guess I added credentials but did not generate a gpg key. If you are having trouble with it I can make one, but could you try and see if you can generate one plz?
