User Story: As a user of Egyptian Arabic (arz) or Moroccan Arabic (ary) wikis, I would appreciate getting better search results from using some or all of the analysis chain used for Arabic (ar).

While working on unpacking Arabic for T294147, I talked to Mike (@MRaishWMF) about some potential ICU folding, and he mentioned some differences between Standard Arabic and Egyptian Arabic and Moroccan Arabic. While there certainly are differences, there are also probably some similarities, such that either or both could benefit from using some parts of the unpacked Arabic analysis chain—at the very least, some of the Arabic-specific normalization should be helpful. Mike has agreed to help with the analysis, too!

Acceptance Criteria:

• Either Egyptian Arabic (arz) and Moroccan Arabic (ary) wikis are configured to use some of the Standard Arabic analysis chain elements, or we have documented the reasons why it turned out not to be a good idea.
