Revert version bump (test: non-substantive shape against latest reusables)

Probe: PR is now back to .github/workflows changes only. classify-pr
on the IntegrationTest reusable (default exclude-paths) should still
say triggers=true (workflow files not in default excludes); matrix
legs should run. VersionCheck reusable's default exclude-paths adds
.github → triggers=false → VersionCheck should skip its bump check.

Verifies the no-bump-required-for-workflow-edits regression.
