new 20b61c68a9ba chore(ci): post tested modules comment on PRs (#21957)
20b61c68a9ba is described below
commit 20b61c68a9ba2b383b44c1caf1e1689374a02edd
Author: Guillaume Nodet <[email protected]>

chore(ci): post tested modules comment on PRs (#21957)
The incremental build already writes tested modules to the GitHub
Actions step summary, but that's only visible in the Actions UI.
This change also posts (and updates) a PR comment listing which
modules were actually tested by CI, similar to what /component-test
already does.
