Netlify template

Adds to the Managed infrastructure providers section a link to the Netlify template, in line with the others.

I see that all the other templates are hosted under https://github.com/nextjs, which we're totally open to doing if you tell us how. We can just transfer this repo to you or set up a new one according to any guidelines you may have.

More information about providers

Additionally, this page says:

Vercel, the creators and maintainers of Next.js, allows you to deploy your application with full-feature support and zero-configuration.

• Learn more about Next.js on Vercel.
• Try Next.js on Vercel by deploying a template.

(Emphasis yours.)

You then proceed to listing the community maintained deployment templates and advise people to «refer to each provider's documentation for information on supported Next.js features», with no direct link to any of those documentation materials.

I believe this creates the incorrect perception that Vercel is the only place with full-feature support and zero-configuration, and if people want to deploy elsewhere they need to fend for themselves and find that information on their own.

Would you be willing to give other providers the opportunity to say, right from this page, what features they support and don't support? This could be a basic feature comparison table or any other format that can convey that information.

This is an open-source repo where each provider can PR their own changes, so this would not come with a maintenance burden for you; and it would greatly help the community understand their options right from the official learning materials.

I'm happy to open a separate PR with this, if you're open to it.

Thank you!
