Bug: TypeError when showing help with Typer 0.12.5 + Click 8.2.0 on Python 3.13.3

Description

When running a Typer application on Python 3.13.3 with Typer 0.12.5 and Click 8.2.0, calling cli().help() or using the rich help formatter results in the following error:

TypeError: Parameter.make_metavar() missing 1 required positional argument: 'ctx'

Steps to Reproduce

1. Install Python 3.13.3
2. Install Typer 0.12.5 (pip install typer==0.12.5)
3. Run the following minimal example:

import typer

cli = typer.Typer()

@cli.command()
def hello():
    """Say hello"""
    print("Hello!")

if __name__ == "__main__":
    cli().help()

Error Traceback

TypeError: Parameter.make_metavar() missing 1 required positional argument: 'ctx'

The error occurs in typer/rich_utils.py in the _print_options_panel function, which calls Parameter.make_metavar() without providing a context argument.

Environment

• Python 3.13.3
• Typer 0.12.5
• Click 8.2.0

After trying to code a workaround I realised that typer developers themselves have pined the wheel.
fastapi/typer#1225

So proposing this fix for the time being.

Tested locally with the new wheels.
