Update git submodules

* Update helpcontent2 from branch 'master'
to 142696bd75353a8b1fa23c6aae08b0d18e807546
- tdf#153560  adjust heading levels for "Up to level" and "Offset"

One content change: A correction to the description of the
"Heading" type. Other changes are neutral in relation to translation.
* The options in the "Format" section are part of that section, so
they should be one level down (h2->h3) in the hierarchy.
- remove <xml-lang>
