feat: add NW Spring results
As requested in #15146, add the recent NWPL Spring competition results.
Changes to the original:
- Remove divisions from lifter names if guests
- Disambiguate some people
- Add various Instagrams from the file and strip them
- Swap some division identifiers (ie. FR-J to FR-Jr)
- Update Cam Little to be u53 in MR-Jr but u59 in MR-O
Closes #15146.
