• js, jsx, ts, and tsx files support nullish coalescing operator syntax highlighting

What steps did you take to test this? This is required before we can merge, make sure to test the flow you've updated.

• http://localhost:3000/s/agitated-shockley-9oxb0?file=/src/App.js should correctly highlight the source code despite the presence of the ?? operator

Notes

1. I manually updated the following files (editing the strings manually)

packages/app/src/embed/components/Content/Monaco/grammars/tmGrammars/TypeScriptReact.tmLanguage
standalone-packages/vscode-extensions/out/extensions/javascript/syntaxes/JavaScript.tmLanguage.json
standalone-packages/vscode-extensions/out/extensions/javascript/syntaxes/JavaScriptReact.tmLanguage.json
standalone-packages/vscode-extensions/out/extensions/typescript-basics/syntaxes/TypeScript.tmLanguage.json
standalone-packages/vscode-extensions/out/extensions/typescript-basics/syntaxes/TypeScriptReact.tmLanguage.json

The files now contain updated regexes for ternary-expression.begin and keyword.operator.logical.tsx. According to microsoft/TypeScript-TmLanguage#768, these are the two syntax rules that are affected by the nullish coalescing operator syntax.

2. I loosely followed the instructions in https://github.com/codesandbox/codesandbox-client/tree/master/standalone-packages/vscode-extensions/out/bundles to regenerate standalone-packages/vscode-extensions/out/bundles/main.min.json: deleted the file, ran the app in development mode, loaded the app in the browser and grabbed the entirety of global.fileReads through the browser js console, and minified the json using an online tool, and re-created the file
3. I followed the instructions in https://github.com/codesandbox/codesandbox-client/tree/master/standalone-packages/vscode-extensions/out/bundles to bump the versions: vscode-extensions/v17 -> vscode-extensions/v18, vscode31 -> vscode32 (applying a global find/replace on the codebase, including minified files)

Caveats

• I couldn't figure out how to point to later version of microsoft/TypeScript-TmLanguage and automatically pull the files from a remote, which is why I just "applied the diff" manually
• I also didn't update the information_for_contributors field of some of these tm files, which refer to specific commits like microsoft/TypeScript-TmLanguage@84238ef; guidance here would be appreciated
• The npm run update-grammars script referenced in https://github.com/codesandbox/codesandbox-client/tree/master/standalone-packages/vscode-extensions/out/extensions/typescript-basics/syntaxes no longer exists, but it appears that it would be capable of pulling the latest version from the upstream Microsoft/Typescript-TmLanguage repo. I noticed that builds is gitignored; perhaps that's why I couldn't find the scripts?
