Fixes #9739

Proposed Changes

This PR displays keyboard shortcuts associated with context menu items in the context menu. In general, shortcuts and context menu items that perform the same function should have the same name/ID; to avoid breaking backwards compatibility, a conversion map was added for preexisting built-in shortcuts.

Refactored this to use associatedKeyboardShortcut as described in #9739. If present, it takes precedence; if not, matching falls back to id <-> name. This allows for lookup to succeed for legacy items without breaking changes, and for new ones the same ID/name should be used.
