Update git submodules

* Update docs/submodules/pharos from branch 'stable/euphrates'
  - Merge "generate_config: Use eyaml to decrypt secret values" into stable/euphrates
  - generate_config: Use eyaml to decrypt secret values

    Note: IDF data encryption is not supported. Supporting that is
    trivial, but it leads to slightly more complicated code, plus it
    breaks support for multiline scalar encrypted data in the PDF ('>'),
    forcing us to define each encrypted value as inline string.

    While at it, fix silly limitation of jinja2 path residing in a subdir
    of CWD.
