Update git submodules

* Update helpcontent2 from branch 'master'
  to 7a45cfda035abefcda03767a4c81f93c69d593b1
  - tdf#33749 - HTML Help pages - reflect changes to cell merge in Calc
    
    Replaced the entire "Format > Merge Cells" submenu with the single
    "Format > Merge and Center Cells" button with all the same behaviour
    it has on the Formatting Bar.
    
    Replaced the "Split Cells" button from the context menu of a selected
    merged cell with the "Merge and Center Cells" button showing the
    current merge status, as it does elsewhere.
    
    Also, add the "Merge and Center Cells" link to the Formatting Bar
    Description Help page. It was missing.
