Update git submodules

* Update docs/submodules/auto from branch 'stable/fraser'
  - Merge "docs: Fix long lines" into stable/fraser
  - docs: Fix long lines

    OPNFVDOCS scripts set max line length to 240 chars. This patch
    shortens long lines to avoid rst validation warnings during Auto
    docs generation.
