[grammar-selector] Overhaul grammar display:
* When set to `true`, `hideDuplicateTextMateGrammars` will hide all grammars except whichever one the user has indicated a preference for — via `useTreeSitterParsers` and `useLegacyTreeSitter` settings, whether global or scope-specific. * When set to `false`, `hideDuplicateTextMateGrammars` will show all grammars, even Legacy Tree-sitter.
