Describe the feature

It would be nice, if the dependencies are not installed so there is no node_modules folder and there is a package.json file, then via a notification it asks you if you want to install them.

I think it'd be better to handle it on language server side - VTSLS could send out a MessageRequest for pop-up and then install dependencies on server side.

@osiewicz : You say to check it here:

zed/crates/languages/src/vtsls.rs

Lines 199 to 204 in 7d905d0

	delegate: &Arc<dyn LspAdapterDelegate>,
	_: Arc<dyn LanguageToolchainStore>,
	cx: &mut AsyncAppContext,
	) -> Result<Value> {

No, I mean that this functionality can be implemented by a language server and we don't need to write any extra code on Zed's side to support it. In fact I think it would make more sense to do it this way.
