Make guides/creating-command-line-tools.rst inclusive #1907

Issue Description

source/guides/
creating-command-line-tools.rst uses an example based on gender, written in a way potentially offensive to nonbinary people. It provides "masculine" and "feminine" as options. It then includes a line

pronoun = "her" if feminine else "his" if masculine or knight else "its"

greeting += f"what's-{pronoun}-name"

This is not nonbinary-inclusive, and specifically there's violent history of applying 'its' to trans people as a means of dehumanization. (Some individuals do use 'it/its' pronouns, but in code or conduct generally "else 'its' " should not be the logic. (they/them/their/theirs are better 'else' defaults in keeping with how people generally refer to someone if gender is unknown.)

This could be remedied by expanding the intial input commands to include nonbinary as an option, and to somehow modify the pronoun logic such as else 'their' though I wonder about just reworking or dropping gender from this example as for instructional purposes it could be any/many things other than gender. Alternatively it could be expanded it to include custom pronouns beyond her, his, their. Higher up in the code the cli takes commands -masculine and -feminine, it could be written to take -nonbinary and have 'Mx.' as the resulting output when a name is provided.

As is, the example may be a negative distraction for some learners, and as such is not in alignment with the PSF code of conduct section that states

"Every member of our community has the right to have their identity respected. The Python community is dedicated to providing a positive experience for everyone, regardless of [...] gender identity and expression [...] "
