Rustup help page changed, so the commands that were based on the old
layout to get the completions were broken
Improved some completions to include a description like "default" or
"installed"
Also added completions for `rustup help`
Hey, it's me, I finally fixed this `use` vs `source` script.nu 😄
Also, I added a few lines of the `custom-completions/README.md` to
explain what happened in my case
Hi!
It's been a long time using nushell completions, It's about time I can
open a PR 😄
I couldn't finish it in one sitting, but I got the know-how, so I won't
be late to complete it. Left a bunch of `TODO`s
More completions coming!
Keep being awesome 🚀
