fix(inno): sign installer with signtool

this effectively disables signing the uninstaller
as somehow inno setup doesn't forward environment
variables to the subshell used to run signtool. As
we can't authenticate using environment variables
that way, we also can't sign with our new
certificate. Future thought will need to be given.
