Change `desc` to `skip`

[karikarshivani]

Using desc in the InSpec logic overrides the description of the STIG rule. To avoid that, change code from:

impact 0.0
desc 'This control is not applicable'

to:

impact 0.0
describe 'This control is not applicable' do
  skip 'This control is not applicable'
end

Controls found with desc:
