Change the ci.yml lint script to use turbo

[NullVoxPopuli]

the previous script, ci:lint, takes over 6 minutes to run on C.I., and doesn't run at all on my laptop :sweat_smile:

The goal of this change is to:

• worst case have lint checking still be faster than 6m.
• best case have lint checking be near-noop (prior to this change, lint always takes 6m, it seems)
• be kinder to the environment
• lean in to human impatience :D

Using turbo, logs are now grouped together under <details>-esque groups:

Lint: Baselines (main branch results)

• 6m9s : https://github.com/starbeamjs/starbeam/actions/runs/6292201602
  • 5m40s of actual linting
• 5m50s : https://github.com/starbeamjs/starbeam/actions/runs/6291893932
  • 5m34s of actual linting
• 7m7s : https://github.com/starbeamjs/starbeam/actions/runs/6286683339
  • 6m39s of actual linting

Lint: This PR

• worst case: ~1m35s faster -- also way more consistent

  • 4m45s : https://github.com/starbeamjs/starbeam/actions/runs/6292841126/job/17082637983?pr=131
  • 4m19s of actual linting

• best case, way faster and < 4s locally (FULL TURBO)

  • 29s : https://github.com/starbeamjs/starbeam/actions/runs/6292665751/job/17082304245?pr=131
  • most of this 29s is installing node_modules
  • 6s of actual "linting"

• average case: around 1m

The average case would then lint only the packages that have changed, which keeps CI as fast as it can be. This is why focusing on package-relative commands is so beneficial -- it allows caching per package, which enables to not do more work than we need to.

• average case -- maybe around 1-2m

A note on average / best cases -- more work needs to happen in https://github.com/starbeamjs/starbeam/pull/132 Because the turbo config is being dirtied more often than it should be. Likewise, we need to be sure still dirty when real things change. So I've added some debugging tips to CONTRIBUTING.md

Marking this as ready for review, though, I'd like to optimize the inputs, as tests directories are getting included for package inputs, and they need to be ignored:

This will be next, assuming turbo either fixes the issue, or tells me what I'm doing wrong :sweat_smile: https://github.com/starbeamjs/starbeam/pull/132
