poc: Run all GitHub Actions on M1 macOS runners

Description 📝

Just a simple POC to run all of our GitHub Actions on M1 macOS runners. Curious to see if we get any significant performance improvements 🤔🚀

👀 very interested to see how this pans out, I wasn't aware you could even get Apple Silicon runners. I'm curious how any non-x86_64 containers perform compared to our current setup

[bnussman-akamai]

Looks like some steps like lint were slower than normal, but I think that's just because dependencies are not cached yet.

test-manager was about 4 minutes faster than normal though 😲

This is great - will speed up test and coverage jobs lots

Coverage Report: ✅
Base Coverage: 81.24%
Current Coverage: 81.24%

Am happy to give this a try! Only concern is something not going well during a release.

I think I remember @jdamore-linode mention we could have duplicate workflows (one runs on unbuntu the other on macos). Since we can enable them or disable them through the UI seems like a good compromise, however instead of managing two identical actions we could store the runs-on in an env variable?

[bnussman-akamai]

I think we decided that it would be easiest to just switch over and not maintain a matrix of operating systems.

What do you think @jdamore-linode?

[dwiley-akamai]

I think it would be fine to make the switch and keep an eye on things

[jdamore-linode]

@bnussman-akamai I agree! I think as long as we merge this with a day or two to spare til the next release, we'll have plenty of time to identify/address any issues

[bnussman-akamai]

After running the tests a few times, I don't think the performance wins are really significant. I think we'll benefit the most with staying on ubuntu-latest for compatibility with various GitHub Actions and stability

We'll start seeing significantly better performance when when drop yarn and node for bun where possible
