What part(s) of the article would you like to see updated?

GitHub Actions merge_group trigger supports branches filter since its beta release in Aug 2022, but it's not documented till now.

I guess the symmetric branches-ignore filter is also supported but didn't check it myself.

One option is to extend current section on.<pull_request|pull_request_target>.<branches|branches-ignore> to cover merge_group and taking care of old anchor name redirection. Or a separate on.merge_group.<branches|branches-ignore> section can be added.
