Suppress error from monaco-editor (#29684) (#29758)

Backport #29684 by @silverwind

Fixes: https://github.com/go-gitea/gitea/issues/29414

I see no way for us to catch this error, so downgrade it until
https://github.com/microsoft/monaco-editor/issues/4325 is fixed, which
will likely take a few weeks to propagate up from vscode.

The entries in `updates.config.js` will make
[`updates`](https://github.com/silverwind/updates) not upgrade these
anymore and I think it's good documentation as well to have the reasons
why we don't upgrade these dependencies.
