Title: Add .md as file endings & use gender neutral pronoun

I wasn't sure of the `index` files so I didn't touch them.

extensions/extended-join-3.1.md used binary gender pronouns which I didn't notice in other files. I am not sure if they are used in other files, but this is the instance I noticed.
