15 minute runtime

[aparlato]

Noticed downstream: This action appears to run extremely slowly and then fail.

This is causing us to waste a lot of our monthly Github Actions minutes.

I dove in a little here to try and understand what is going wrong and it appears that there are issues in 2 places:

• actions/setup-node@v2 is taking too long (upgrade to v4 might fix)
• mapbox-gl-style-linter at the latest (v0.2.0) isn't installing appropriately with npm

I have had luck using yarn as a package manager and upgrading actions/setup-node, however, I'm still not clear on what the underlying issue is, so want to hold off on implementing this as the fix.

Downstream, we are disabling the action in favor of running linting locally for now as this requires further investigation.
