Summary

This pull request lets a checkboxes or radio buttons option use a mrkdwn description, as the option object and checkboxes element docs show. Until now, the docs payload (a plain_text option text with a mrkdwn description) failed to compile.

Closes #1765.

• MrkdwnOption (used by Checkboxes and RadioButtons) now takes a plain_text or mrkdwn text and description.
• PlainTextOption (used by overflow, select, and multi-select menus) keeps a plain_text-only description, as the docs require.
• Adds tsd cases: checkboxes and radio buttons accept a mrkdwn description, and overflow and static select reject one.
• Supersedes feat(types): allow mrkdwn descriptions on checkbox and radio button options #2742, which widened description but kept MrkdwnOption.text as mrkdwn-only, so the docs payload still failed to compile there.

Testing

1. Run npm test --workspace=packages/types and confirm tsd passes.
2. Revert packages/types/src/block-kit/composition-objects.ts and confirm the new checkboxes and radio buttons cases fail.
