Remove sentences with links to private `github/copilot-partners` repository

[rajbos]

See the link to the copilot-partners repo here:

preview-sdk.js/README.md

Line 225 in 2b49829

See additional documentation about Copilot errors at https://github.com/github/copilot-partners/blob/main/docs/copilot-errors.md.

.

Not sure where that should point to.

Oh good catch! The linked repository is private, that's why you get a 404.

I think for now we should remove these links. We have public documentation now but there is no docs on the syntax for each of these event types

Thanks again for opening this issue!

8c434bc modified this to remove the reference in place of the appropriate documentation in the GitHub Docs.

I think we're good to close this now! ⚡
