Add list of executables to verbose list

[ChadThackray]

Sometimes I forget the executable names for packages I've installed with basher or there might be multiple executables. So I added a printout similar to how the uv package manger handles uv tool list.

Example output:

$ basher list -v
bats-core/bats                 (https://github.com/sstephenson/bats.git)
- bats
