automation: delete code related to Python 2.7 support
The building of Inno and WiX installers took a python_version argument
that allowed us to specify "2" or "3" for the major Python version. Since
we no longer support Python 2, we can delete this argument and everything
feeding into it.

githelp on a single command should succeed
$ hg githelp -- commit
hg commit
$ hg githelp -- git commit
hg commit
githelp should fail nicely if we don't give it arguments
$ hg githelp
abort: missing git command - usage: hg githelp -- <git command>

$ hg githelp -- git
abort: missing git command - usage: hg githelp -- <git command>

githelp on a command with options should succeed
$ hg githelp -- commit -pm "abc"
hg commit --interactive -m 'abc'
githelp on a command with standalone unrecognized option should succeed with warning
$ hg githelp -- commit -p -v
ignoring unknown option -v
hg commit --interactive
githelp on a command with unrecognized option packed with other options should fail with error
$ hg githelp -- commit -pv
abort: unknown option 'v' packed with other options
(please try passing the option as its own flag: -v)
