Readonly help text field

[Radiergummi]

For some resources in our Nova app, creation requires a little background info. Often, that is either too important to cram into a field help, or the message is too long for that, or is generally related to a resource, not a single field. It would be good to be able to add a description to the screen which provides additional help when creating or updating resources.

One option I could imagine would be a new Resource::help(NovaRequest $request): string (getting passed the request to allow e.g. different content depending on the edit type), which could be displayed below the page heading on form screens:

A second variant would be a new readonly field, akin to the existing Heading field, which would display the text inline. Ideally, that field would render Markdown content (named Description, maybe), but a pure string implementation (called Paragraph?) would work too.

Either way, having a built-in facility would complement the existing Heading field, and make Nova apps more approachable to non-technical folks.
