Fix incorrect analytics mapping for UTDs.

[pixlwave]

As pointed out by @BillCarsonFr, #3442 messed up the mapping here.

Additionally upgrades the CI runners to macOS 15 given the failure in https://github.com/element-hq/element-x-ios/actions/runs/11727089995/job/3266732078, caused by actions/runner-images#10703.
