[6.x] Update currencies dictionary with all circulating currencies

[tdrayson]

While using the dictionary in my project, I noticed several currencies were missing for countries I was trying to add. This PR adds 40 missing currency codes, sourced from the Wikipedia list of circulating currencies, to align the dictionary with the current ISO 4217 list:

AOA, AWG, BBD, BMD, BSD, BTN, CUP, FJD, FKP, GIP, GMD, GYD, HTG, KGS, KPW, KYD, LAK, LRD, LSL, MNT, MRU, MVR, MWK, PGK, SBD, SCR, SHP, SLE, SRD, SSP, STN, SZL, TJS, TMT, VED, VUV, WST, XCD, XCG, and XPF.

Also updates PEN label from "Peruvian Nuevo Sol" to "Peruvian Sol" to reflect the 2015 currency renaming.

Thank you for the PR. You've just updated the language file, which doesn't make the values appear in the field. Please feel free to update this PR after you've implemented the changes in the dictionary and actually tested it.

Hey, sorry @jasonvarga, first time contributing to Statamic. I've opened a new PR #14520, confirmed and tested it works and also updated both the translation file and the dictionary file.

Awesome, thanks.

I am sorry to say that the wikipedia list of circulating currencies is in no way a relevant source of information. Wikipedia cannot be listed as a relevant source for anything. ISO4217 is, absolutely. With the appropriate link
