we decided only to remove macos

[ourownstory]

Makes sense, thank you!
Until we remove matplotlib support (or potentially longer), I suggest we keep windows test to catch any plotting package dependency/build issues.

[noxan]

Windows tests fail frequently due to "This probably means that Tcl wasn't installed properly."

Also why should there be any different dependency or build issues on windows?
