vue: Use latest available @vue/language-server package

[rowanwins]

This PR relates to #9846 which pinned the @vue/language-server package to a version approximately 12 months old. This PR brings behaviour inline with how other JS language extensions works by pulling the latest available package.

I have tested on Zed 0.155.2 and it now seems to be behaving.

Last I checked, there were changes in v2 of the Vue language server that broke certain aspects of the functionality:

The Vue bits of the language server work, but the TypeScript stuff doesn't. And they have a separate language server plugin you can use to add Vue support to tsserver, but then they also put out another release after v2 that added back the old built-in TypeScript support.

It's possible that they have remedied this since last I looked, but we'll need to do due diligence to make sure all of the workloads are still working as expected.

I don't know the full context, but upstream claims this issue volarjs/volar.js#186 was fixed by vuejs/repl@f9f650a.
Don't know if there were additional issues.
