Cannot get non-formatted help output if Rich is installed

First Check

• I added a very descriptive title here.
• I used the GitHub search to find a similar question and didn't find it.
• I searched the Typer documentation, with the integrated search.
• I already searched in Google "How to X in Typer" and didn't find any information.
• I already read and followed all the tutorials in the docs and didn't find an answer.
• I already checked if it is not related to Typer but to Click.

Example Code

import typer


cli = typer.Typer(rich_markup_mode=None)
print(f"rich markup mode is: {cli.rich_markup_mode}")

@cli.command()
def foo():
    print("hi")

if __name__ == "__main__":
    cli()

Description

As the title says, it doesn't appear possible to get a non-formatted help output if rich is installed, even when rich_markup_mode is implicitly or explicitly set to None. I'm not quite sure I'm following the flow correctly but I think the issue comes from this logic:

https://github.com/tiangolo/typer/blob/04eba6b70203287176d2823753513226bf778872/typer/core.py#L671-L678

Which is set for TyperCommand and TyperGroup, and only considers whether or not rich is installed. Uninstalling rich gives me the help output I'm looking for, but I'd like it installed to use elsewhere in my project.

Hi! Yes, this does seem to be a bug in typer. This PR attempts to resolve the issue, and covers the same code path you've mentioned as well: #726. The PR is currently work-in-progress but should be in a good state to merge relatively soon.

Oops, I didn't think to search PRs, just the issues 🤦

Thank you for the reference, will keep an eye out!
