vue: Fix Vue.js language server not starting (zed-industries#11743)

This fixes zed-industries#10871.

The introduction of zed-industries#11412 broke Vue.js language support, since it made
Zed rely more heavily on correct language name -> language ID mappings,
which the Vue.js extension didn't have.

 # REFACTOR is explicitly disabled, as vue-lsp does not adhere to LSP protocol for code actions with these - it
