Add TypeScript Worksheet to open-vsx please!

I tend to use Windsurf's IDE by Codeium. They use an implementation of VSCodium, and VSCodium cannot use the official MS extensions library that traditional VS Code accesses. Instead, you have to publish the package to open-vsx. The instructions are at the below link.

OR go directly to open-vsx:
