Update git submodules

* Update helpcontent2 from branch 'master'
- tdf#121532 Don't use non-standard `echo -n`

At least the version of echo used to build TDF's LO 6.2.0.3 release apparently
doesn't understand that non-standard option and printed out "-n" verbatim,
generating a broken languages.js.  (Though my local macOS 10.14.3 /bin/echo does
understand that option.)
