Hide add-matcher and remove-matcher from actions job logs (#36520)

Hides `::add-matcher::`, `##[add-matcher]` and `::remove-matcher` in job
step logs. These are used to configure regex matchers to detect lines
that should trigger annotation comments on the UI, currently unsupported
by Gitea and these have no relevance to the user.
