Bump Dapper, Moq and xunit to latest patch releases

- Dapper 2.1.35 → 2.1.72
- Moq 4.20.70 → 4.20.72
- xunit 2.9.2 → 2.9.3 (both test projects)

Applied locally instead of accepting Dependabot PRs #11, #12, #13
because those three conflicted after the Microsoft-group merge and
Dependabot rebasing would have queued three more CI runs. The three
PRs will auto-close once this lands on main.

All 13 unit tests and 14 integration tests (+1 skip) still pass.
