Type fixes in app (part 1) (#16545)

* Fix paths of imports

* Process not-found.vue as ts

To prevent the following error from 'vue-tsc':
  error TS6504: File '/Users/pascal/Development/directus/app/src/modules/insights/routes/not-found.vue.js' is a JavaScript file. Did you mean to enable the 'allowJs' option?

Note: We could also enable 'allowJS' but since this is the only js file
this seems to be a more fitting fix

* Drop hljs language definition for GraphQL (now in core)
