workflows/triage: CI-build-dependents-from-source changes

* Only label `ghc` and `go` formulae on major/minor version bumps by
  checking when the alias changes. This may break if we no longer need
  the alias, but it avoids having to introduce version parsing.
* Ignore labeling formulae when only revision bumped or even situations
  where formula has an existing revision (as most cases we want to test
  on version bumps and those will always remove/reset the revision).
  One situation this doesn't help is non-bump PRs on a formula that has
  no revision stanza.
* Set `allow_any_match` to label PRs when Alias and Formula need to be
  modified or when other revision bumps are needed.
