cask/audit: reject new casks requiring Rosetta

macOS 27 is now the latest stable release so, per docs/Acceptable-Casks.md, new casks needing Rosetta 2 are no longer acceptable. Error in audit_rosetta when a new cask's artifacts are x86_64-only.

Drop the pre-Big Sur guards: Big Sur is the oldest allowed macOS. The depends_on macos: guard also skipped every cask without one, as nil&.maximum_version.to_s is "", which sorts before "11".

[x] Have you explained why you'd like these changes included, not just what they do?

[x] For bug fixes, have you given step-by-step brew commands to reproduce the bug?

[x] Have you written new tests (excluding integration tests)? Here's an example.

[x] Have you successfully run brew lgtm (style, typechecking and tests) locally?

[x] I did not use AI/LLM to create this PR, or I disclosed the tool/model below and reviewed its output; I did not attribute commits to AI and will answer maintainer questions and review comments myself without AI/LLM.

Claude with Opus 5.5 at High effort, with local review and testing.
