build: fix vue peer dependency

[ferm10n]

Description

vite-plugin-vuetify depends on @vuetify/loader-shared, which expects a peer dependency of vue.

Without the peer dependency, the loader will rely on package hoisting to place the dependencies in an accessible location which is not guaranteed to happen.

I encountered this myself while working on a monorepo that includes vue2 and vue3 packages, and got this error:

❯ yarn dev --host
failed to load config from [...]/vite.config.ts
error when starting dev server:
Error: @vuetify/loader-shared tried to access vue (a peer dependency) but it isn't provided by its ancestors;
this makes the require call ambiguous and unsound.

Required package: vue
Required by: @vuetify/loader-shared[...]#npm:1.7.1

Ancestor breaking the chain: vite-plugin-vuetify@[...]#npm:1.0.2

Sometimes this problem manifested like this instead: (including for future googlers)

(0 , vue_1.camelize) is not a function
4:23:39 p.m. [vite] Internal server error: (0 , vue_1.camelize) is not a function
  Plugin: vuetify:import

I assume it imported the wrong vue here...

Workaround

# .yarnrc.yml
packageExtensions:
  vite-plugin-vuetify@^1.0.2:
    peerDependencies:
      vue: "^3"
