windows end-to-end documentation

[cantsin]

Adds documentation on how to run end-to-end tests on windows. Admittedly this process could be made easier, especially if we pull in dbmate usage in the container. Also systemd on windows is a Thing Now. But, in the interests of expediency, here's what worked for me.

Also threw in a quick bug fix for the Makefile.
