💡 Suppress modules in Rich tracebacks

[harkabeeparolus]

It would be useful to provide our users with the Rich traceback suppress parameter. This would allow developers to suppress uninteresting stack frames in tracebacks from other Python frameworks.

For example, python-github, which gives a verbose traceback with many frames on a simple GitlabAuthenticationError. I would like to be able to suppress this entire call stack, but it doesn't work:

#! /usr/bin/env -S uv run --script

# /// script
# dependencies = [ "python-gitlab", "typer", "rich" ]
# ///

import gitlab
import rich.traceback
import typer

# This code does nothing; Typer will override it
rich.traceback.install(suppress=[gitlab])

def main():
    gl = gitlab.Gitlab()
    print(gl.pagesdomains.list())

typer.run(main)

But with this pull request, you can suppress modules directly with Typer():

#! /usr/bin/env -S uv run --script

# /// script
# dependencies = [ "python-gitlab", "typer" ]
# ///

import gitlab
import typer

app = typer.Typer(pretty_exceptions_suppress=[gitlab])

@app.command()
def main():
    gl = gitlab.Gitlab()
    print(gl.pagesdomains.list())

app()

I'll put this in draft as long as the tests are failing 🙏
