Reapply develocity

[ribafish]

This PR reverts PR #25335, which removed the Develocity configuration. It also includes a proposed fix for ant jobs not starting due to groovy scoping.

Note: If possible, please test the ant jobs fix before merging :)

Relates to issue #25322.

This is missing develocity volume.

• I've applied your change wrt secrets for ant stages in Added basic develocity setup #25322 #25336

And now this PR and 25336 differ for:

• in 25336 required volume is mounted
• in 25336 extensions are not enabled by default but on request.
• Jenkinsfile in 25336 is actually used in pipeline.

Hence, I propose for you to close this PR and discuss in 25336.

#25342 (comment) - @pzygielo I'm not sure what this means...

• That the old Jenkinsfile was used in the build, and not the modified one.
  Build is green, but it's the same trap as in Added basic develocity setup #25322 #25324.

Note: If possible, please test the ant jobs fix before merging :)

I pushed the commit as the branch to origin.
Again - it's green, but
