[Pages] Include documentation for Node Version in nextjs/deploy-a-static-nextjs-site.mdx

[schemburkar]

Included additional documentation for updating node version for a next.js static site using .nvmrc

Summary

Additional documentation to update Node.js version used is Cloudflare builds by default.

Recent Next.js versions require a minimum Node.js version to be used in builds. Most other documentation on specifying Node.js version applies to a full Next.js site. For a static website, the simplest approach is to update the .nvmrc file as Cloudflare builds use nvm for detection of node version

Fixes #22529

How can I customize these reviews?

Check out the Hyperlint AI Reviewer docs for more information on how to customize the review.

If you just want to ignore it on this PR, you can add the hyperlint-ignore label to the PR. Future changes won't trigger a Hyperlint review.

Note specifically for link checks, we only check the first 30 links in a file and we cache the results for several hours (for instance, if you just added a page, you might experience this). Our recommendation is to add hyperlint-ignore to the PR to ignore the link check for this PR.

why is this sh (rather than plain or text)?
Is it an error message?

[schemburkar]

Yes, error message from build when not specifying a node version on a new default setup.
Reason Cloudflare defaults to 18.17.1 while NextJS defaults to minimum 18.18.0

[vicb]

That's one way to force a version, there are other.

Not sure if that's something we should document? Is it not really related to Cloudflare?

yes I'm aware, although most other documentation only works for Cloudflare workers which is different than the Static NextJS setup for Cloudflare Pages.
And since any new NextJS setup for static website hosted on Cloudflare Pages will need this, thought it will be better to document the same.

Feel free to decide otherwise
