Add more candidate directories to be added to $PATH

[unixorn]

Description

• Bump version to 1.3.3
• Check for ~/homebrew/bin and ~/homebrew/sbin to cope when homebrew is installed in a user's home directory. Closes The plugin does not work properly if we change the destination of the homebrew installation #28
• While we're in there, check for /usr/local/sbin, /opt/homebrew/sbin, /opt/local/sbin, ~/bin and ~/sbin directories too.

Type of changes

Checklist

• All new and existing tests pass.
• Any added/updated scripts added use #!/usr/bin/env interpreter instead of potentially platform-specific direct paths (#!/bin/sh and #!/bin/bash are allowed exceptions)
• Added/updated scripts are marked executable
• Scripts do not have a language file extension unless they are meant to be sourced and not run standalone. No end-user should have to know if a script was written in bash, python, ruby or whatever. Not including file extensions makes it easier to rewrite the script in another language later without having to change every reference to the previous version.
• I have confirmed that the link(s) in my PR are valid.
