Why not directly creating a PR for this change?
Furthermore, what about the following simplification?
filename: "(\\.(m|c)?js$|\\.es[5678]?$)"

@med-ab looks like you created the PR on/targeting your own fork rather than here. Was that intentional?

[med-ab]

@Kissaki not intentional, i tried again though, how about now?

@med-ab:
It didn't work, because no new PR showed up in this upstream repository.
Maybe you have a look again into the following two GitHub documentations:

1. https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/fork-a-repo
2. https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request-from-a-fork
