Vite

[NullVoxPopuli]

Converts the docs and test-app to vite using the vite codemod from mainmatter.

Also migrates from fastboot to vite-ember-ssr since fastboot doesn't work with vite.
(and vite-ember-ssr is quite a bit more ergonomic)

each app:

1. Run codemod
2. run lint:fix
3. Remove v1 addons (fastboot, fastboot-testing, ember-cli-code-coverage, etc)
   2. ember-try replaced with @embroider/try, CI updated accordingly
   3. ember-cli-sass removed
   4. ember-cli-github-pages removed
4. add vite-ember-ssr
   1. Migrate each vite app to minimal, shedding compat (required)
   2. type=module the apps
