Fix ERB.new depracation notices

[Fabian1976]

This fixes these 2 deprecation warnings which appear on each puppet-run:

Info: Applying configuration version '1711367415'
C:/ProgramData/PuppetLabs/puppet/var/lib/puppet/provider/base_dsc_lite/powershell.rb:153: warning: Passing safe_level with the 2nd argument of ERB.new is deprecated. Do not use it, and specify other arguments as keyword arguments.
C:/ProgramData/PuppetLabs/puppet/var/lib/puppet/provider/base_dsc_lite/powershell.rb:153: warning: Passing trim_mode with the 3rd argument of ERB.new is deprecated. Use keyword argument like ERB.new(str, trim_mode: ...) instead.

Could you please merge it and publish a new version on the forge?
