Description

In order to T401245: Rewrite GrowthExperiments in a way that it can be enabled on all Wikipedias automatically, we need to have a plan on what things need to change. The best way to get that is to move forward with enabling GrowthExperiments on a new wikipedia wiki and noting down all the manual changes that are necessary for that.

The last time that this was done was for T364130: Enable Growth mentorship at igl.wikipedia.org.

Acceptance criteria:

GrowthExperiments is enabled at one new Wikipedia wiki: Nigerian Pidgin Wikipedia (pcmwiki)
It is documented in this task what manual steps have been necessary at that wiki to make GrowthExperiments work there

After comparing this list to the list of wikis with Add a Link model availability, and also looking at Wiki Comparison data, I’m going to suggest Nigerian Pidgin Wikipedia (pcmwiki) due to the size rank, 3 monthly active admins, and >0 monthly new editors.

However, if we run into any blockers, we can also consider:

Gun Wikipedia (guwwiki)
Wayuu Wikipedia (gucwiki)
Farefare Wikipedia (gurwiki)
Pa'O Wikipedia (blkwiki)
Tyap Wikipedia (kcgwiki)
