Figure out how to automatically publish to Sonatype

[mdedetrich]

What is currently missing?

Currently the project is using sbt-release in order to do publishing (see https://github.com/aiven/guardian-for-apache-kafka/blob/main/build.sbt#L223-L239) . This is currently done as a manual step however ideally it should be done automatically.

How could this be improved?

sbt-github-actions allows you to automatically publish a library within CI (see https://github.com/djspiewak/sbt-github-actions#integration-with-sbt-ci-release). This uses another plugin instead of sbt-release so we should figure out what is the most ideal way to do this. I believe the way this is done is by creating a pull request that changes the version from a SNAPSHOT to a whole release which triggers a build.

The credentials for our sonatype account should also be stored as github actions secrets

Is this a feature you would work on yourself?

• I plan to open a pull request for this feature
