feat: update nuxt docs

[illiyyin]

Hi guys, this is my first open-source contribution pr, let me know what should I do

I tried to use tiptap in my small project using nuxt, after I followed the current instruction. Looks like the code is still using nuxt 2, and I'm using nuxt 3 so I got an error, and then it looks like the code needs to be updated

I don't find the solve on the issue, but I found these issues on the tiptap main repo

• [Documentation]: Update Nuxt example for 3 version tiptap#4965
• docs for Nuxt 3, preferably using composition API with SFC and v-model tiptap#3125

After I tried to debug, my code working.

This pr still needs to be updated tho, since this part here is using embed. I can't find the code on this repo

@illiyyin is attempting to deploy a commit to the Tiptap Team on Vercel.

A member of the Team first needs to authorize it.

Thanks for your contribution! It's a great improvement for Nuxt 3 devs, but it overrides the Nuxt 2 guide. So there would be no installation guide for Nuxt 2 developers. Am I right? Or does your guide work for Nuxt 2, too?

In my opinion, I would either:

A. Create different pages, each with a guide for nuxt 2 and nuxt 3 respectively.

B. Mention, in the Nuxt guide, the differences in setup between Nuxt 2 and Nuxt 3. So that Nuxt 2 devs can still set up Tiptap.

@bdbch what do you think is the best option?

I would make it dependend on whether Nuxt 2 is not supported anymore or people still actively use Nuxt 2.

If it's the latter than I'd go with two separate pages, yes.
