Feature Description

A clear and concise description of what you want to happen under what circumstance.

After Overleaf Website offloaded the spell checking to the frontend, this feature was no longer available in overleaf-workshop (issue). @iamhyc suggested opening a local replica and using local spell checker, but that would miss the benefits of using overleaf features (compile, PDF preview, etc).

It turns out that it's possible to use Code Spell Checker. You just have to enable the custom file scheme overleaf-workshop is using (detailed instructions)

    "cSpell.enabledSchemes": {
        "overleaf-workshop": true
    }

I think it would be nice to add these simple steps (or some kind of pointer) somewhere in the documentation (the README? the wiki?) because that would massively benefit users looking for this feature.

I can make a PR if needed.

Thanks for the great work! Please feel free to open PR if you have time

It's glad to know that code spell checker can support custom schemes!

@QianrenLi I see there is a update API on workspace configuration (link), please check if we can enable the configuration for "cSpell.enabledSchemes" by default.
