refactor(cli/rule): don't report unused suppression comments

[Conaclos]

Summary

This PR brings several improvements to the --rule CLI option:

• Unused suppression comments are now ignored when --rule is specified
  This was really noisy because running a single rule makes all suppression comments - except those of the run rule - unused.
• A lint/ prefix can be sued to select a group or a rule.
  This allows the following execution:

  biome lint --rule=lint/suspicious
  biome lint --rule=lint/suspicious/noDebugger

• We report a diagnostic when --rule=nursery is passed.
  Users should enable a specific nursery rule instead.

Test Plan

I added tests.
