fix: Add support for Powershell and CMD on all supported runners (#18)

Closes #17.

This PR brings the following changes:
- Now it is possible to use Jython 2.0 and 2.1 on `ubuntu` and `macos` runners!
- Added support for Powershell on all runners (previously only on `windows` runners)
- Added support for Windows Command Prompt (`cmd`) on windows runners. Notice that because of how the `cmd` handles single quotes it only works if no single quotes are used to enclose parameters: `jython.bat -c "print 'Hello world'"` will work, while `jython.bat -c 'print "Hello world"'` will not.
- Renamed `jython.bat` to `jython.ps1`. To use Jython on the powershell now you have to specifically call `jython.ps1`
- Add tests for Bourne shell (`sh`), Windows Command Prompt (`cmd`) on Windows runners and Powershell (`pwsh` or `powershell`)
