Allow description parameter for row fields

[skysarwer]

Row fields currently do not accept an admin.description parameter.

There are many use cases where fields organized in rows would have some common features that would benefit from helper text that is directed at both fields.

Descriptions assigned to nested fields within a row also often break the row layout and auto-collapse it to the normal view.

Yes, the row can be wrapped in a group field, which can effectively achieve the same thing, however this changes the database schema and can be more difficult to iterate with in a more mature project.

Another option is the UI field, but that requires defining a custom Field component and importing new types just to add a simple description.

Allowing the row field to accept a description parameter, consistent with other fields, seems like a simple, elegant and intuitive option that I imagine would be a quick win regarding time to implement vs. value it provides.
