✨ unsort the completions in git checkout

[AucaCoyan]

motivation

Hi! This is something I wanted since #14424 of nushell/nushell landed.
Unsorted completions on the git checkout command

The problem

is that git checkout accepts lots of things: commits hashes, filenames, local branches and remote branches. Since the mentioned pr all the completions were sorted, but for this command it didn't make sense.
I used git switch to checkout a branch for the time being, but it's a little annoying that you can't push "unsorted" completions on a command.

the result

With the help of ysthakur and weirdan, I managed to achieve this:

git checkout <tab>

before: (these are sorted)

after: (these aren't)

How?

Citing the docs:
https://www.nushell.sh/book/custom_completions.html#options-for-custom-completions

    {
        options: {
            case_sensitive: false,
            completion_algorithm: prefix,
            positional: false,
            sort: false,
        },
        completions: [cat, rat, bat]
    }
}

and I passed a table to the completions key, instead of a list.

    completions: $table_of_checkouts
