Updating documentations for ANTLR 5

ftomassetti commented 9 months ago

This PR does a combination of minor things to update references to ANTLR4 into references to ANTLR5.

It updates information on contributing, specifying that from the beginning ANTLR 5 is using the DCO mechanism and removing the historical contribution agreement
remove the changelog file, not been updated since 2014
remove several files documenting dropped targets
update the document on releasing ANTLR very coarsely, by removing paragraphs about dropped targets and changing the references to ANTLR 4 into references to ANTLR 5

Moved to the #26 instead:

It renames Antlr4MojoTest into Antlr5MojoTest
from POM, remove the configuration for cleaning the swift target, as it has been dropped

Can we have separate PRs for code changes and doc changes ?

Sure, I extracted #26 to focus on code and infrastructure, and I have updated this PR to focus exclusively on documentation

In this case, after I performed the changes requested, should I press the button Re-request review or is it enough to add a comment in the PR?

I guess the former expresses clearly that from your POV it is ready ?

Plus technically I think it triggers a review workflow, which maybe helps close the previous review. Let's find out ?

Thanks, I pressed the button

It does help close the previous review 😄
