Improve "maven-publish.yml"

[Marcono1234]

Hello,
maven-publish.yml could probably be improved:

1. Improve command line parameters, see also Improve maven.yml #538
2. Link to https://github.com/actions/setup-java#apache-maven-with-a-settings-path should be placed directly above settings-path: because it is irrelevant for everything else
3. Add link to https://github.com/actions/setup-java#publishing-using-apache-maven in header comment (or to GitHub Help: Publishing Java packages with Maven)
4. Remove redundant step name: Build with Maven, deploy already includes package so it essentially runs package (and all phases before it) twice
   Edit: deploy would skip compiling (since package already did this), but would run tests again.
5. Add --batch-mode to deploy to prevent output which is intended for interactive console
6. Write out -s as --settings to make it easier to understand for users who are not familiar with all command line options
7. Change name "Publish to GitHub Packages Apache Maven" to "Publish to GitHub Packages with Maven" to be consistent with other message
8. It might be possible to run deploy with -Dmaven.install.skip=true to skip installing the package to the local repository since that could cause issues when a cache step is used and a large number of the packages of the project accumulate (only happens if the version of the package changes frequently). Though would be good if someone with more Maven deployment experience could confirm this.

Let me know if you want me to write a pull request.

I'm not a maven user, but a pull request for these changes would be most welcome.
