feat(ci): refactor build workflow

[jsjoeio]

This PR does some major refactoring to our build.yaml workflow, specifically the prebuild step. The two themes of this PR are:

• parallelization
• fail-fast

It splits up the prebuild jobs - lint, format, etc - and runs them in separate jobs so they can run in parallel. It also adds a new step to each which cancels the entire workflow if any of them fail. This way, we can fail-fast and not waste developer time or CI minutes. Plus, it allows us to run these prebuild checks in parallel to building code-server which means faster feedback loop.

Looks good to me, I am going to run it on my branch again to double check the changed files stuff then will approve.

[code-asher]

I like the rename.

[code-asher]

The installation tests are failing but I think it is due to an older change, not this PR. I will push up a PR after this merges to fix it.

I am getting lint and build errors but I am not sure why...maybe unrelated to this PR? Investigating.

The Typescript lint check seems to run every time now?

[code-asher]

False alarm on the lint step, I thought the changed files worked from commit to next commit but I think it compares to main each time. So I think it is working.

I think we might need fetch-depth: 2 though for when the branch gets merged otherwise the checks would not run on main (they would only run on the PR) based on:

IMPORTANT: For push events you need to include fetch-depth: 0 OR fetch-depth: 2 depending on your use case.

[jsjoeio]

So I think it is working.

Nice!

I think we might need fetch-depth: 2

Ah interesting. If understanding right, you want me to add that to every step in build.yaml where we checkout code-server?

Only on the steps with the changed-files action (so lint-ts and lint-helm).

Done!

[code-asher]

My build issues seem to have disappeared so maybe it was a cache issue? If it crops up again we can take another look but I think we are good to go. Nicely done!
