[BUG] rich.traceback.install(width: int) is ignored when stderr is not a tty

See original GitHub issue

Rich traceback output is forced to a width of 80 columns when there is no tty on neither stdout nor stderr:

./im_going_to_crash.py  2>&1 | cat

This is in spite of me setting the width in rich.traceback.install to something else. It is completely ignored and seem to simply use the value 80.

Possible inconsistency: The function default value seem to be set to 100, different from rich.console.Console which seem to default width to None.

Rich version: 10.16.2

When there is no tty, Rich is unable to detect the width of the terminal, and so defaults to a maximum of 80 characters.

If you know the width, you can set the COLUMNS environment variable.

Also, when running my script, I can use COLUMNS to reduce the width, but it seems to cap out at 100 regardless of what I set for width (I assume since that is the default).
