test(e2e): select docs dry-run checks

[yxzhaao]

Summary

• include docs unknown-flag and legacy format compatibility checks in the e2e-dry-run selector
• keep the cases focused on executable dry-run behavior, not generated help text

Root cause

The e2e-dry-run job selects tests by DryRun|Regression, while these cases did not match the selector.

Validation

• go test -v -count=1 -timeout=5m ./tests/cli_e2e/docs -run '^(TestDocsFetchCommentsFlagRejectedDryRun|TestDocsCommandsFormatCompatibilityDryRun)$'\n- go test ./tests/cli_e2e/docs -list 'DryRun|Regression'\n- git diff --check
