feat(nuxt)!: rewrite nuxt module

[pi0]

This PR rewrites the Pinia+Nuxt module for best Nuxt 3 and Bridge compatibility 💛

Testing repo with published package: https://github.com/pi0/nuxt-tests/tree/pinia

Changes:

• Add pinia as a dependency -- Nuxt modules are supposed to be standalone and provide integration out of the box
• Migrate back to kit -- However using kit is not documented yet and might change, it will make stability much better than not using it and without it we have to inline bridge support
• Split vue 2 (bridge) and vue 3 plugins
• Remove deprecated ctx.pinia
• Nuxt 2 without bridge is not supported anymore
• Drop .$nuxt support to prefer useNuxtApp

TODO:

• Use resolveModule from kit to respect search path for pinia
• Detect bridge || nuxt 3 (Support requires: bridge module meta nuxt/nuxt#11869)
• Fix config types
• Fix runtime types
• Auto import for pinia

Is there something I can help with? (It's the last missing piece for my migration to bridge)

Hi! I'd love to help too if there's anything I can do 🙂

Thanks, @yassilah @tobiasdiez 💚 PR is pending for Nuxt 3 module tooling. Expect it ready soon :)

Any chance to see this PR merged in the near future? :) Seems like the following code is never taken into account with Nuxt 2 + Bridge:

const piniaSharedStatePlugin: Plugin = ({ $pinia }) => {
    $pinia.use(({ store }) => {
        console.log("REGISTERED PLUGIN");
    });
};

export default piniaSharedStatePlugin;

I understand, that you have a lot of work on Nuxt3 RC, but could you clarify the current status of this PR?
