Improve, tweak and fix nutrient names in nutrients.txt

[October-Food-Facts]

This comes from a Slack discussion. It's a very bad time to post this, as the nutrients are currently broken, but I still wanted to get a part of it out of the way.

Changes main name consistency, capitalization, including in English, synonyms, spellings in Portuguese and suggests removing the unsupported pt_pt lines too.

• Apply these changes to taxonomies/nutrients.txt

• • B5

pt: Vitamina B5 (Ácido Pantotênico), Vitamina B5 (Ácido Pantoténico), Ácido pantotênico, Ácido pantoténico, Vitamina B5, B5

Although there are doubts, the European Portuguese legislation (here) spells with a hyphen, and therefore so does the Portuguese Nutrition Association (here).
