typo in Chronicle of Edessa

[dlschwartz]

@jedwardwalters Compare https://syriaccorpus.org/57#Head-id.76 with text of line 25 and footnote 1 here https://archive.org/details/chronicaminorapa00guid/page/678. The Corpus has one thing, the mss has something else, and Guidi recommends a third reading. Looks like the current Corpus just contains a typo. Not sure how best to encode this given difficulties with rtl. Happy to bounce ideas around though.
