`[PSModuleInfo].Site/Website` should get module website metadata

[StartAutomating]

This should be an open-ended description of site data. However/and, since a property like this can include a path to module-relative data (and since it is a popular set of frameworks), data in this section should take after Hugo and Jekyll

This will return a PipeScript.Module.Website psobject.
