Updated module dependencies

To enable the Wake flag, we need ConfigurationManager module. This was
in the module manifest in Required Modules, however get-pc is functional
without ConfigurationManager so it didn't make sense for get-pc to
fail importing if ConfigurationManager wasn't present. Removing it
from Required Modules and importing it at the bottom of Get-PC.psm1
allows the import to fail silently and the lost functionality isn't
reported until user attempts to use the Wake flag (which is a good
thing).
