Fix syntax errors in the suites

Changes:
    - Fixes the following

    1) Keyword 'SeleniumLibrary.Page Should Contain'
       expected 1 to 2 arguments, got 3.
    2) No keyword with name 'CLI Get Nameservers' found.
    3) Keyword 'BuiltIn.Run Keyword And Return Status'
       expected at least 1 argument, got 0.
    4) Setting 'Documentation' is allowed only once.
       Only the first value is used.

Tested:
     - Ran with --dryrun and check is clean
