Enable CI for Windows

[jwoertink]

In #906 I tried about 100 different times to get Windows to go green on the CI, and I was met with 100 different walls. For not Windows CI is disabled, but we will eventually need to get this added in.

Some of the issues I've run into:

• Can't use postgres as a service since containers don't run on Windows.
• Node isn't installed by default on Windows like it is for Mac and Linux
• Which also means yarn isn't installed by default...
• The system_check fails to run on Windows
• yarn is not a valid command error
• Can't find the lucky binary even after being added to PATH. Is it looking for lucky.exe?
• Windows supports different shell types like pwsh. Do we have to add duplicate commands for each step just on windows?
