Update git submodules

* Update extensions/wikihiero from branch 'wmf/1.30.0-wmf.2'
  - Fix styles queue violation for "ext.wikihiero.Special"

    The same module is explicitly being loaded twice, once just the
    styles, and again with the JS/messages/dependencies as well.

    This is wasteful and also unsupported.

    Move the two style rules to the main stylesheet and load the
    proper styles module it belongs to instead.
