Update deployment targets for tests (#4145)

Updates the deployment targets for a couple of test suites to match
their corresponding frameworks.

Specifically updates for `RevenueCatUITests` and for `AllAPITestsTests`
(yeah, I don't love the name either, but that's the _test suite_ tied to
the AllAPITests framework)
