@mathiasbynens should we add Apple M1 builds before GitHub actions support it?

I worry that this change would make it even harder to find a suitable Chromium revision across all platforms, since this increases the number of different platforms. Speaking of which, would we also need to update https://github.com/puppeteer/puppeteer/blob/main/utils/check_availability.js?

Good point. I don’t think we should ship this until we have a solid testing story. We could land this as an opt-in feature, but then I’d like us to also do the following:

• explicitly add a TODO to our main Actions workflow, pointing to Add ARM + MacOS target to be able to use on self-hosted runners actions/runner#805
• update the documentation to state that this support is experimental

Let's close this PR in favour of #7546 which seems to include changes to the check availability script as well.
