Add the Nuxt VueFire example repos to the docs.

[BenJackGill]

What problem is this solving

I was having a lot of problems with SSR and App Check. Took me a few days to stumble upon these fantastic example repos which solved the problem for me:

• https://github.com/posva/nuxt--vuefire-example-blaze-plan
• https://github.com/posva/nuxt--vuefire-example-spark-plan

Proposed solution

I suggest you prominently feature these repos at the top of the in the Nuxt Getting Started doc section to ensure other people can easily find this valuable resource.

They are actually in the deployment page since the complexity comes from deploying more than developing. We could add them to the top too.
