feat: add languages to ts servers plugin settings

[sacki5]

This will make it possible to use the Vue plugin in hybrid mode which is the recommended way since v2 of vue language tools. Also the hybrid mode setting will be deprectated in v3 of vue language tools.

This pr will make it easier to enable hybrid mode but will still need some additional settings.

// Settings to enable hybrid mode. (after this pr)
{
  "languages": {
    "Vue.js": {
      "language_servers": [
        "vtsls",
        "..."
      ]
    }
  },
  "lsp": {
    "vue-language-server": {
      "initialization_options": {
        "vue": {
          "hybridMode": true
        }
      }
    },
  },
}

Would be neat that in the future to be able to have the hybrid mode as default and work out of the box after you install the Vue plugin.
