Fix various issues with names in string interpolation (#89246)

## About The Pull Request
Commit messages should be descriptive of all changes.
The "incorrect `\The` macro capitalization" was intentional when it was
added, but as far as I know TG says "the supermatter" rather than "The
Supermatter," so it's incorrect now.
This is completely untested. I don't even know how you'd go about
testing this, it's just a fuckton of strings.
Someday I want to extract them and run NLP on it to catch grammar
problems...

## Why It's Good For The Game
Basic grammar pass for name strings. Should make `\the` work better and
avoid cases like `the John Smith`.
