provide completions for git remotes with remote as prefix

[meganrogge]

Sanity checks

• My issue relates to a specific CLI completion spec (e.g. git checkout is missing options in git completion spec). If your issue is more general, please create your issue here: withfig/fig
• I have searched github.com/withfig/autocomplete/issues and there are no duplicates of my issue
• I would like to work on this.

What CLI tool does this relate to?

git

Which statement makes the most sense?

There is a bug with this completion spec

Issue Details

1. When I type git commit and request completions, I expect to see origin/branch_name for example.
2. This code prevents that from happening:

   autocomplete/src/git.ts

   Lines 92 to 96 in 7828841

   	if (insertWithoutRemotes && name.startsWith("remotes/")) {
   	name = name.slice(name.indexOf("/", 8) + 1);
   	description = "Remote branch";
   	}

These changes allow that to show up in the completions list:

I'm wondering if you are open to this contribution.
