[gby] Move ʻ 02BB to auxiliary

Gbari [gby] orthography uses the apostrophe, or sometimes turned comma, for the elision of prefix e- in nominalization.

In some works U+02BB MODIFIER LETTER TURNED COMMA is used, for example in Harley & Rosendall 2022 [1] or in Bible for Children translations [2], but this doesn’t seem to be consistent.

In one of the Bible for Children translations [3], the elision is represented with ‘ U+2018 LEFT SINGLE QUOTATION MARK on the title page of the PDF and with ʻ U+02BB in the rest of the document but the nested opening quote is also represented with ʻ U+02BB:  “Ke Zafnu de mula nyigo yi é gna ɗye, ʻZhi!’ Ke zanɗye wa wo ɗye ʻZhi!’ Ke zanɗye nuwna miwnu wo wo nya wo zhi. Ke zanɗye a ɓawo nya, wo go nuwna wyewye nyi tantaki.”

The 2023 digital version of the 1956 Gbari New Testament [4], albeit using an old orthography, uses ' U+0027 APOSTROPHE.

It’s not clear if ʻ U+02BB or ' U+0027 or ‘ U+2018 should be in the base characters exemplar as it is not listed as a letter from the Philip & Seshi 2004 orthography [5] in Alerechi & Chiemezie 2019 [6].
