[COOL BUG READ FOR MORE INFO] Fix vaccines not working in chem masters by giving Fungal TB's vaccine (and others) a name + Add unit test for duplicate chem names + Rename fake beer + Ratio (#65241)

Reagents work based off their name. Vaccines and fungal TB's vaccine had the same name.

Renames fake beer from "Beer" to "Beer...?", because it's been used 10 times this entire year and it's obvious it doesn't matter.

Fixes some typos in some other chemical names, where typepaths were not correct.
