Update git submodules

Update git submodules

* Update docs/submodules/pharos from branch 'master'
  - Moving check-jinja2 to pharos.

    Securedlab will be going away now that we can encrypt strings
    (eyaml)

    we need to check jinja2 PDF templates that will be moving into pharos
    This adds one pod yaml files and fixes paths in check-jinja2.sh

    After this is merged I can create a jenkins job for pharos.

    Then I can start moving pdf files into the pharos repo
