feat(z): include cwd folders in suggestions for zoxides `z` command

[ScottRobinson03]

What

The existing spec for the z command includes folders of the cwd for rupa/z, but not zoxide's z. This PR adds autocomplete suggestions for zoxide's z command and therefore resolves aws/codewhisperer-command-line-discussions#114.

I also added icons as per the following:

:file_folder: ... = not in zoxide history, but in cwd/pwd :floppy_disk: ... = in zoxide history AND cwd/pwd :floppy_disk:/... = in zoxide history, but NOT cwd/pwd (notice the leading / in path)

Example:

Known Issues:

For some reason I can't seem to consistently get all of zoxide's cwd suggestions above the non-zoxide cwd suggestions. I'm using the priority key to try and achieve this, but it doesn't seem to work here for some reason? Would appreciate assistance in debugging this.

The issue with priority not working is likely history which will result in previously selected items to be at the top even when a high priority is set, this is something I will need to look into fixing but at the moment this should be fine.
