meta: Fix changelog script (#12069)

Actually we should check for the changelog commit, which we look for by
checking `-meta` and `changelog` in the commit message. (Not perfect,
but good enough hopefully...)

I noticed it was not correctly picking up all commits while a release
was in progress before.
