README.AI_modules: Update to speak of 'tex' instead of 'threaded'
Reply To cazfi
likely there's no need to further changes to master README.AI_modules after that patch, but under this ticket only older branches need updating.
This patch meant for S3_0 and S3_1.
README.AI_modules does not mention tex AI at all, though it should in several places. Those same places mention deprecated 'threaded' AI, so likely the best solution is to just replace those mentions (i.e., to leave 'threaded' mentions out already)
This came up as I'm working on completely dropping 'threaded' from master ( #42268 ) - likely there's no need to further changes to master README.AI_modules after that patch, but under this ticket only older branches need updating.
