Take on John edits

> I just read through all of MOD (mod.ttl), creating a [fork](https://github.com/graybeal/MOD/tree/main) so I could make all the [typographical changes](https://github.com/FAIR-IMPACT/MOD/compare/main...graybeal:MOD:main) I could identify (29 diff changes, a few with multiple word changes).
