Add cms-umbraco example

[kjac]

This PR adds a sample blog powered by Umbraco CMS.

Umbraco CMS v12 (released June 29) adds headless capabilities directly to the Umbraco core. This PR showcases how a blog can be built using Umbraco CMS as backing content source.

This example is not to be mistaken with the Umbraco Heartcore example. Umbraco Heartcore is a SaaS platform built on top of Umbraco CMS.

A demo of this example can be found at https://nextjs-umbraco-sample-blog.vercel.app/.

• The "examples guidelines" are followed from the contributing docs (see https://github.com/vercel/next.js/blob/canary/contributing/examples/adding-examples.md)
• The linting passes (running pnpm build && pnpm lint, see https://github.com/vercel/next.js/blob/canary/contributing/repository/linting.md)

Hi @ijjk,

Is there anything I can do to ease the review of this PR? If it helps anything I can setup an Umbraco site with a publicly available API for testing.

Hi Next.js peeps 👋 is anyone able to help us get this thing reviewed?

Hi @leerob,

I can't entirely figure out what it is you'd like me to update 🙈 the example does use draft mode, though. And it is essentially a copy of the cms-wordpress example. Or, at least that was the intent 😄

I did spot a few missing TypeScript rewrites in the preview API handling, so I have fixed those now. And I also did a re-linting to keep the example up-to-date with the current style preferences.

Please let me know if you need me to do further updates to this 👍

Hi Vercel/Next.js team (ping @leerob)
What's the status on this one? Been talking to quite a few customers that could be customers of both front-end hosting from Vercel and CMS hosting from Umbraco, who'd be interested in seeing this PR merged in.

Following up - do you want to address the lint errors so we can get this merged?

[kjac]

Hi @leerob 👋 thanks for following up. I'll have a look at fixing the linter errors this week - hopefully one of the next few days.

[kjac]

@leerob should be good to go now 👍

[leerob]

Could you run the check-examples script as well? CI is still red

[kjac]

@leerob aha! Looks like the link in next-env.d.ts was out of date (ref #68534).

I've updated the link now.
