removing the macron: wakashū -> wakashu throughout edit

The standard (and far more common) reading is wakashu, not wakashū. This is attested not only in primary texts but in reference works such as the Kadokawa kogo daijiten, the Kabuki jiten, and all of the major modern Japanese-Japanese dictionaries (Nikkoku, Kōjien, etc). No need to over-correct and use the macron. Unfortunately I don't know how to correct an error like this when it is in the main entry/URL itself. 184.189.221.201 (talk) 05:18, 4 May 2023 (UTC)Reply
