📚 Description

We've been discussing migrating to pnpm in our move towards full pnpm support. This PR implements it using --shamefully-hoist and --strict-peer-dependencies=false; we can remove these flags when possible.

We also have the opportunity to lose a lot of weight in the monorepo if we remove lerna - not sure how possible that is @pi0 but worth mentioning; it's now only used for the actual release. (lerna replaced with local scripts for bumping rc)

Contributors notes

If you have already cleaned the repository locally, run this to migrate:

npm run cleanup && corepack enable && pnpm install && pnpm build:stub

You can also safely remove top level .yarn directory.

Script updates:

• yarn stub script is changed to pnpm build:stub
• yarn dev script is changed to pnpm play

📝 Checklist

• I have linked an issue or discussion.
• I have updated the documentation accordingly.

This is really convincing as well as pnpm speed 🚀

Netlify build seems going wrong (not related to pnpm but since deps are now shared it is happening)

3:12:12 PM: [error] [nuxt] [request error] [unhandled] [500] app.ssrContext.nuxt.vueApp.config.globalProperties.$pinceauSsr.get is not a function

pinceauSsr usage wrong?

3:12:12 PM: [error] [nuxt] [request error] [unhandled] [500] Cannot read properties of undefined (reading 'url')

Hint: useQuery is called with req instead of event somewhere (github module and another place)
