Expose webhook during serve for use with external data

[mattwaler]

Is your feature request related to a problem? Please describe.

There is no easy way to trigger an update / rebuild during the serve command when external data changes.

This would be extremely useful in two ways:

• Once external webhooks are configured, would trigger a rebuild/reload locally when content changes (better DX overall)
• Would allow developers to create a "staging" site on another server that is constantly rebuilding with the newest content for preview before triggering a production build

Describe the solution you'd like

It would be awesome if the --serve command exposed a webhook that would trigger a rebuild, similar to when actual files change. Something like {url}/__rebuild

Describe alternatives you've considered

Any alternative would be awesome if it accomplished the same goal, allowing an external webhook to trigger a rebuild.

@mattwaler This was a while ago, but why did you close it? I've been looking for something like this for Strapi / 11ty local development and haven't found anything (maybe I've been looking in the wrong places).

I think #3085 and 11ty/eleventy-dev-server#70 should help with this, if anyone is reading and interested.
