Also, the docs reference using mix_stderr=False for CliRunner, but this is not longer available in Click 8.2.0

I haven't looked over this PR, but we did just add a new doc page about supporting multiple versions in Click, with an example for the get_metavar signature change. https://click.palletsprojects.com/en/stable/support-multiple-versions/ If there are other parts that you think we should document, or need help figuring out compatibility with, please let us (Click maintainers) know.

Thanks a lot for offering help @davidism and especially for writing those docs! 🙌

I'm currently debugging the output showing errors for required parameters, with the update it doesn't show what was the (missing) required parameter, I probably have something wrong here... still debugging. 🤓 This was mainly about updating output formatting.

Now I'm debugging something related to shell completion. The shell completion thing was only about accessing the result.output.

The challenge was finding something related to the new support for enums in Click. In Click 8.2, choice types can use enums, but they expect the command to pass the name of the enum, not the value. And Typer has supported enums but using the value as the input instead of the enum name. This was handled by creating a custom Typer class type for choice that handles the input with the old Typer behavior.
