Update SHA for DanaKit

[marionbarker]

Summary

The previous feat/dana version would successfully build on iOS 15, 16 and 18 phones but for iOS 15 and 16 phones, the option to select Dana as a pump was not shown. For the iOS 18 phone, the option was shown and worked as expected.

This PR modifies the minimum iOS deployment to 15.1 and runs successfully on multiple Loop test phones.
