Remove pom fix - and add check workflow

[koppor]

Current build output:

* Where:
Build file '/home/runner/work/afterburner.fx/afterburner.fx/build.gradle' line: 98

* What went wrong:
Execution failed for task ':generatePomFileForMavenJavaPublication'.
> Could not apply withXml() to generated POM
   > wrong number of arguments

It is not clear whether we need that fix 4 years later. Let's try without.
