Hi @JounQin - thank you for submitting this PR! Can you explain why you've opened this PR and what this fixes or what benefits this brings? I'm not familiar with resolver-typescript

@jsjoeio As you can see at https://github.com/cdr/code-server/pull/4546/files#diff-3894e4104cda190617684d0dc5d55e39e49c63cc6955edf4a446b91ae086bbd2, eslint-import-resolver-typescript resolves .ts/.tsx/.d.ts and @types/* packages correctly and there is no need to ignore "unresolved" errors anymore.

[jsjoeio]

Ahh! (That code was before me)

Now I see. Thanks for fixing/replacing this! You can ignore the Docs preview but as long as the rest of CI passes (it should), we can merge!

[jsjoeio]

Thank you so much for doing this!

[JounQin]

@jsjoeio Shall we merge then?

Shall we merge then?

Yes! Apologies I was out Thurs/Fri but should get this in today :D Thanks for the bump!
