re-enable pana baseline checking (pending build fixes)

[pq]

See, for example: https://github.com/dart-lang/linter/pull/2502/checks?check_run_id=2087774664

Chatting with @jonasfj, this will require a bit of local debugging. (Just haven't gotten to it yet...)

[pq]

Interestingly, this runs w/o issues locally. 🤔

[~/src/repos/linter] (master) $ dart tool/pana_baseline.dart
...
   {
    "id": "null-safety",
    "title": "Support sound null-safety",
    "grantedPoints": 0,
    "maxPoints": 0,
    "status": "passed",
    "summary": "### [*] 0/0 points: Package and dependencies are fully migrated to null-safety, and will be awarded additional points in a planned future revision of the pub.dev points model.\n"
   }
  ]
 },
 "scores": {
  "grantedPoints": 90,
  "maxPoints": 100
 }
}

{grantedPoints: 90, maxPoints: 100}
Baseline check passed ✅
... you have a new baseline! 🎉 Consider updating tool/baseline/pana.json to match.

Here's the CI error:

@jonasfj : any thoughts?

[jonasfj]

Are the sources located in /home/runner/work/linter/linter/lib or /home/runner/work/linter/lib ?

Maybe an extra linter folder was given?

Just a qualified guess from seeing:

Invalid argument(s): Provided content does not align with expectations.
No dart files found at: /home/runner/work/linter/linter/lib`"

[pq]

Right. The path is definitely wrong. Here's where it's set:

  var output = await Process.run('pub', [
    'global',
    'run',
    'pana',
    '-s',
    'path',
    Directory.current.path,
    '-j',
  ]);

This used to work? 🤔

Disabled w/ dart-archive/linter#2518 pending some investigation.
