Idea: List modified view files

I just got this warning in https://github.com/wordpress-mobile/WordPress-iOS/pull/22000

(source: https://github.com/wordpress-mobile/WordPress-iOS/pull/22000#issuecomment-1809310967)

I wonder if it would be useful to list the view files that have been modified?

To prevent it becoming a visual mess when many files have been modified, we could cap the list to `n` items:

> View files have been modified, but no screenshot is included in the pull request. Consider adding some for clarity.
>
> Files: `AView.swift`, `AnotherView.swift`, `OneMoreView.swift`, plus 5 more.

Start from the warning shown in WordPress-iOS pull request 22000 and locate the Danger plugin code that emits it. Check how modified files are identified, then add a capped list of modified view filenames with an overflow count; done means the warning remains readable and matches the proposed wording.
