Make the gradle check comment more compact (opensearch-project#11151)

Continuing in the spirit of opensearch-project#9699, this makes the gradle check comment
less verbose while containing all the same information. The goal is to
reduce visual noise on the PR feed and maybe allow for more comments
before GitHub starts hiding older comments behind the "load more" link.

This is super subjective so happy to hear any opinions if the previous
format is preferred.
