Move Module publication to powershellgalery.com and use PoSh spec format

[rusanu]

• gallery.uipath.com is incorrect host. It gives instructions on how to install the module as a Studio library, which is not the case for the PoSh module (not to mention that is deprecated and likely to be removed)
• The published nuspec is incorrect for PoSh. The files are incorrectly placed in lib/net452, which is not the location for PoSh modules. The files should be in the root and there should e a psd1 manifest so that Import-Module works correctly
  • Remove the unneeded files from the nuspec (Test binaries)

The ModuleVersion in the psd1 must match the nuger version...
