More consistent subcommand names/terminology

We talk about installing and removing plugins, but use add and rm. ls to list, and usually just run fisher to update (not exactly #527). This can be confusing. Starting in 4.0, I invoke fish's law of discoverability and plan to deprecate add, ls, and rm, in favor of install, update, list, and remove.

• fisher add → fisher install
• fisher → fisher update
• fisher rm → fisher remove
• fisher ls → fisher list

Thank fish for autocompletion, it's not like we have to type all that every time, e.g., fisher i + Tab will autocomplete install for you and so on.

Implemented in 4.x. 🎉

Are the old commands still supposed to work? The 4.0 release notes say fish add was deprecated, but using it errors out with "fisher: unknown flag or command: "add" (see fisher -h)".

@nirvdrum I suppose you are using the latest Fisher? add and rm were deprecated in 4.0, and no longer work on 4.1. 😉

[nirvdrum]

Okay. I thought maybe it was a bug because there's no mention in the 4.1 release notes about them being removed. Deprecating in a major version and then removing in the very next minor version (released only five days later) caught me off-guard. I'll update my Ansible config to lock down the fisher version better.

Good point. Just added a note. 👍
