chore: don't cancel concurrent main builds

[gregmagolan]

Fixing this in all our rulesets.

This updates the GHA ci.yaml concurrency block to match all of our other rule sets. In particular, the cancel-in-progress is updated to not cancel in progress main builds ${{ github.ref_name != 'main' }} so that if two commits land on main back-to-back the 2nd one does not cancel the first if it is still running CI.

Oddly I got the following checksum error on the test-release CI job:

Fixed in 2nd commit

[gregmagolan]

Please update the commit body with the motivation and reasons behind this change and split into two PRs for landing.

Looks like main was broken on the last landed commit by this PR https://github.com/aspect-build/rules_py/pull/333. I'll pre-factor the fix into a separate PR.
