Add Git commit SHA to artifacts using buildnumber-maven-plugin (#18227)

[gayatrikate04]

This pull request introduces the buildnumber-maven-plugin to the Apache Beam project to include the Git commit SHA in the MANIFEST.MF file of the generated artifacts. This update helps in identifying the commit associated with each build and ensures traceability.

The changes are made to the pom.xml file, where the plugin is configured to retrieve the Git commit SHA and include it in the artifact’s metadata.

This PR solves issue #18227 by adding a mechanism to automatically attach the Git commit SHA to the built artifact.

I don't know this well enough to know if there is any risk. @Abacn do you know?

There is some misunderstanding here. maven-archetype is shipped as source codes, used as template project. When user work on such project, there is no assumption they will use git or want this traceability on their own project. I think we should close this.
