Removed unnecessary desc statements

[karikarshivani]

For tests such as:

 desc 'This control is not applicable'
 describe 'This control is not applicable' do
   skip 'This control is not applicable'
 end

desc statements do not make a difference and may cause issues with inspec json and delta.
Controls containing unnecessary desc statements have been updated to:

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

Thanks to @ejaronne for running this locally! Attaching reports here for reference:

• remove-desc branch
• main branch

lgtm! Thanks! (See the personal runs internally, of main vs this branch to show that it doesn't throw a problem)

Looks good to me. Approved!
