After enabling the Contribute entry point to the existing wikis where section translation was enabled (T371692), we may want to enable it by default when a new Wikipedia is created.
Currently, new Wikipedias get Content translation available automatically and access to the mobile experience with Section Translation is provided with a semi-automated process (T371420).
As part of this ticket, we want to (a) provide an automatic (or semi-automatic, at least) process that enables the Contribute entry point on newly created wikis, and (b) check the recently created wikis thar were not covered with the previous enablements and enable the feature there too.
