Update git submodules

* Update docs/submodules/pharos from branch 'master'
  - [daisy] network template: Fix set inside loop

    Previous implementation fails in older versions of py-jinja2.
    See related bug reports [1, 2].
    Since `networks.update` on its own is enough, stop assigning its
    result back to 'networks'.
