commands: better install status help formatting (#41527)
Before (hard to read, doesn't fit on small terminals):
:
```console
  -I, --install-status  show install status of packages
                        packages can be: installed [+], missing and needed by an installed package [-], installed in an upstream instance [^], or not installed (no annotation)
```
After (fits in 80 columns):
```console
  -I, --install-status  show install status of packages
                        [+] installed       [^] installed in an upstream
                         -  not installed   [-] missing dep of installed package
```
