Provide doc page(s) for our common model errors from Pydantic

[tomschr]

Affected Documentation Section

New Error topic, related to #158.

Suggested Change

When Pydantic find a validation error, it gives you this message:

For further information visit https://errors.pydantic.dev/2.12/v/extra_forbidden

There you can find additional information.

I think this is a great idea to provide more information. When you run docbuild and get a bunch of error messages, it may be overwhelming. Providing a link which gives you the reason and a solution may be a way to deal with this.

Additional Context

Some idea that needs to be discussed:

• Each error should be stored in a separate page.
  Although the page may be small, it helps to make it visually more readable and accessible.
• Each error page should follow the same structure:
  • name of the error
  • Culprit
  • Solution
• Maybe create a top-level "errors" directory besides developer and reference.
