Update git submodules

* Update extensions/TemplateData from branch 'wmf/1.38.0-wmf.17'
  to dccfd7096e6d3e2fd83e0b03a1d458039f168710
  - Allow aliases to be integers in addition to strings
    
    Parameter names in a template can be numeric. While it makes a lot of
    sense to force a specific format in the TemplateData JSON (i.e. only
    strings), it's inconvenient and confusing if numbers are rejected for
    being "invalid".
    
    Effects of this patch:
    * The incoming JSON is allowed to contain numbers in the aliases
      array.
    * However, the API normalizes these and forces all aliases to be
      strings, as it was always documented.
    * The editor component accepts anything in the aliases array, but
      forces all aliases to be strings. Again, as documented.
    * Note that it was never possible to use numeric keys in the `params`
      list. This patch is only about aliases.
    
    At the moment this is a somewhat "hidden" feature. We might or might
    not update the documentation to officially allow numeric aliases.
