Windows installation tip

[alexanderankin]

While the website (https://sdkman.io/install) says to augment Git Bash for Windows with MinGW, I had success with simply installing "zip for windows" (http://gnuwin32.sourceforge.net/packages/zip.htm), unzipping the folder (careful - do it with unzip -d - otherwise you'll have to rm -rf manifest/ contrib/ man/) and adding the bin folder from that zip into my $PATH.
