Vite 3 support

[Artur-]

Is your feature request related to a problem? Please describe.

This plugin seems to work with Vite 3 but installing it is a bit of a hassle as it has

  "peerDependencies": {
    "vite": "^2.0.0"
  },

As a result npm install complains that

npm ERR! Found: [email protected]
npm ERR! node_modules/vite
npm ERR!   dev vite@"v3.0.0-beta.4" from the root project
npm ERR!
npm ERR! Could not resolve dependency:
npm ERR! peer vite@"^2.0.0" from [email protected]
npm ERR! node_modules/vite-plugin-checker
npm ERR!   dev vite-plugin-checker@"0.4.5" from the root project
npm ERR!
npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.

Describe the solution you'd like

Expand the peer dependency to cover Vite 3 and pre-releases of Vite 3

Describe alternatives you've considered

Other possibilities would be

1. Remove the peer dependency
2. Create a new version of the plugin only for Vite 3

Not sure which one is preferable here

I'll test does the plugin works fine with Vite3 out of the box tomorrow. If it works fine, I'll add ^3 support and release a patch version quickly.
