Update action.yml

Documented the expected prerelease identifiers in the composite action—preid now explicitly lists common values (alpha, beta, rc, next) and notes that leaving it blank skips prerelease tagging. This preserves validation guidance without reintroducing the linter issue from a choice input. Lint remains clean.
