perf(linter): lazily normalize capitalized-comments text (#28481)

Instead of eagerly normalizing text (causing allocations), only
normalize text when first accessed.

On local fixtures:


Metric | Before → After
-- | --
Allocations | 187,675 → 157,156 (−16.3%)
Allocated bytes | 17,279,585 → 15,605,488 (−9.7%)
Maximum peak bytes | 11,334,860 → 11,334,440
