In webpack we have a little bit different police for contributor, I think ideally we should use the same across all repos

[avivkeller]

I’m not following your review, is it blocking this, I don’t understand the concern?

[evenstensberg]

@avivkeller what he means is that we have workflows standardized across the org and maybe some maintainers of certain repos don't like it

[avivkeller]

I see. Unlike other .github files, workflows are not synced across the entire organization.

Repos still need to 'opt-in' to this workflow by calling it.

Let's use this in webpack and webpack docs repo
