Script for adding curent path to `zoxide` complete

まず external_completers.md を読み、外部 completer の例がどのように示されているかを確認します。issue で言及されている引数なしの場合とパスプレフィックスの場合を含め、提案された Nushell スニペットを検証します。ドキュメント化された例が zoxide の補完とともにカレントディレクトリのエントリを確実に追加できれば完了です。

I like using zoxide as a replacement for cd, so I also like having the tab complete have the current dirs in the directory in addition to the zoxide complete.

I'm not too sure in my own nushell code, so I don't want to make a pull request, but I'd like to share how I added the current dir to my zoxide complete.

let zoxide_completer = {|spans|
  let path = ($spans.1 | glob $"\(?i\)($in)*" | where {path type | $in == dir} | each {path relative-to (glob "." | first)})
  let zoxide = ($spans | skip 1 | zoxide query -l ...$in | lines | where {|x| $x != $env.PWD})
  ($zoxide | prepend $path)
}

this addition to the completer allows you to do this:

The first two entries are from the current dir, the second two are from zoxide.

There are a few places this script can fail. Firstly being with the path relative-to command. It will straight up fail if the prefix can't be found. I have an immutable distro so my /home/user folder is linked to the /var/home/user folder. This makes it unreliable to use $env.PWD as this will be different from what glob returns, so I just glob . instead, lol. Also, I'm unsure if spans always return more than one element. It seems to work with no arguments, but I don't know how it works.

I'm sure there are better ways of doing this and such, but it works for me. Just wanted to share if anyone wanted to refine it and add it to the external_completers.md file.
