Use the newer ERB.new usage for Ruby v2.6 or higher

[gemmaro]

Hello,

This patch suppresses the ERB.new warning when calling serverspec-init with newer versions of Ruby:

$ serverspec-init
...
Vagrant instance y/n: n
Input target host name: pi
 + spec/
 + spec/pi/
 + spec/pi/sample_spec.rb
.../lib/serverspec/setup.rb:155: warning: Passing safe_level with the 2nd argument of ERB.new is deprecated. Do not use it, and specify other arguments as keyword arguments.
.../lib/serverspec/setup.rb:155: warning: Passing trim_mode with the 3rd argument of ERB.new is deprecated. Use keyword argument like ERB.new(str, trim_mode: ...) instead.
 + spec/spec_helper.rb
 + Rakefile
 + .rspec

Reference:

• Ruby 2.6.0 Released - Other notable changes since 2.5 ¹

  Passing safe_level to ERB.new is deprecated. ...

• Ruby Issue Tracking System - Deprecate $SAFE support in ERB and let ERB.new take keyword arguments for it ²

Thanks,
