:sh tab completion cycles through directory names only, not file names or program names

[pbnj]

Summary

Typing :sh followed by tab, helix shows and cycles through directory names only; it does not show files or cycle through them and it does not cycle through program names.

Here is a GIF demo:

• :open shows the current files & folders available
• :sh only sees folders
• A common use-case is to :sh <program> <file_or_folder> but lack of tab completion for program names and file names cripples the :sh feature.

Reproduction Steps

In helix:

• :sh <tab>

It's currently configured to use the directory completer:

helix/helix-term/src/commands/typed.rs

Line 2341 in 63dcaae

completer: Some(completers::directory),

I'm not sure why that completer is used vs the filename completer though (completers::filename)

What would be the expected behavior here? I would imagine also a completer that looks through things the user has in their $PATH to be useful.
