chore: update GH Actions workflows

[felix-seifert]

This PR is meant to upgrade the different GH Actions workflows to use new versions of existing actions and use new functionalities of these actions.

Changes other than formatting:

• Update actions/checkout to version 4
• Update actions/setup-java to version 3
• Use cache for Maven
• User Amazon Corretto JDK distribution
• Ignore being triggered by changes in .gitignore and *.md files
• Remove usage of already archived samuelmeuli/action-maven-publish@v1
• Perform same action as samuelmeuli/action-maven-publish@v1 by adding necessary release credentials to actions/setup-java@v3 and calling mvn deploy manually

I tested the changed workflow triggered by pull_request locally. Due to the needed secrets for the push workflow, I could not test the releasing properly.

LGTM, I guess we notices if release doesn't work after merge...
