Issue: x86 Mac try bots fail to build infra-dialog
Labels: team-infra,P2,triaged-infra

### Type of Request

bug

### Infrastructure Environment

LUCI / Devicelab

### What is happening?

infra-dialog is failing to build. Totally guessing, but maybe Xcode 16 got put on the bot at some point and automatically upgraded `MACOSX_DEPLOYMENT_TARGET` for the infra-dialog project to 14, since Xcode 16 requires 14. `MACOSX_DEPLOYMENT_TARGET` is not strictly set in the project
