What does this pull request do?

Adds the previously unknown skill caps for Minuet and updates the calculation.

How we got here:

Players complained about the potency of Minuet 4 being weaker than 3.
A PR was made and merged by Mowford at LSB to address this: https://github.com/LandSandBoat/server/pull/5477
During the collaboration for this PR I reached out in my discord for testing on the matter to provide the missing retail data.
Shynoe did this testing, shared it in Discord, and the wiki was updated. https://www.bg-wiki.com/ffxi/Category:Minuet
This PR is thus the result of this journey into Minuet.
