Update rich-click version to 1.9

[mirpedrol]

Description of feature

The new version of rich-click 1.9 includes an update to the sorting of options and commands in the help message. This will simplify our code, which currently implements a workaround to achieve the same result. See the issue comments for more details https://github.com/ewels/rich-click/issues/200#issuecomment-3175386819
