Update git submodules

* Update helpcontent2 from branch 'master'
  to 8539d61c5ecca6748e4734671a86783de5fdd4b2
  - Resolves: tdf#130719 add "note" about loading and overwriting styles
    
          - drop existing "warning" under overwrite (because
              it simply repeats what the function is doing).
          + added sentence to overwrite explanation to mention
            that no warning message is given when overwriting.
          + Replaced "warning" with "note" that explains what
              styles actually get loaded.
          + update to <h2>
