Update git submodules

* Update docs/submodules/armband from branch 'master'
  - [docs] Remove redundant information

    Armband and fuel documentation have been the same for E release.
    Instead of duplicating everyhting, make references to Fuel from armband
    docs. I removed the scenario folder as it should not have been here in the
    first place, otherwise the folder structure is kept as is.
