What does this pull request do?

Changes the drop rate of Ro'meave Spring Water from Very Rare to Rare

Currently on LSB it is set to 1% which doesn't match the data we do have.

Taking a look at FFXI DB, the base drop rate without any TH is setting at just under 5%, trending up to 6.6% with TH2, and lastly over 9% with TH3+

Taking a look at the treasure hunter chart, Rare aligns almost perfectly, wheras Very Rare does not match at all.
