Update git submodules

* Update docs/submodules/pharos from branch 'master'
  - Merge "[PDF] check-jinja: cleanup, compact output"
  - [PDF] check-jinja: cleanup, compact output

    The Pharos git repo already has a CI verify job for `yamllint`-ing
    the PDF files (check-jinja input yaml), so drop that check and keep
    linting only output YAML files.

    While at it, slightly rework the output log to make it easier to
    read.
