[Traceback] Add a suppress_filenames option for suppressed files

[lazarcf]

I'm using fastapi and the traceback is enormous with a lot of stuff I don't ever see myself needing ( example : https://bpa.st/OPHPI )

I've subclassed RichHandler and Traceback to suppress the filenames but it would be nice to have an option on RichHandler and other classes that have the tracebacks_suppress option to not render the filenames of suppressed files.

Here is my solution/hack if anyone else is interested : https://bpa.st/FTK6U . Basically just copied the code from rich and added lines 69-70
