macOS consistently failing on the CI for a number of tests

[russellwheatley]

First macOS CI test failure: https://github.com/firebase/flutterfire/actions/runs/3045676242/jobs/4907530924

The last successful macOS test run: https://github.com/firebase/flutterfire/actions/runs/3044555313/jobs/4905079521

Note: The test environment is the exact same.
Both running on the same image: https://github.com/actions/runner-images/releases/tag/macOS-11%2F20220906.1

You can see the environment here: https://github.com/actions/runner-images/blob/macOS-11%2F20220906.1/images/macos/macos-11-Readme.md

No changes to FlutterFire nor the firebase-ios-sdk on this date that would make the following tests fail:

A few things worth noting:

4 tests have the error code SecItemAdd (-34018) which is a keychain sharing entitlement error code. Testing locally shows the other 2 tests are failing because of SecItemDelete error which is associated with keychain access.

2 of the plugins with failing API affected rely on App Installations whilst the other plugin with failing API is App Installations.

See this table

I suspect the issue lies with this product.

We will keep this issue open until there is a change in the environment that sees this error disappear.

Ran the failing API locally and received the same error. Once keychain sharing capability was included on the test app, the tests passed. See console logs:

In another Keychain access issue, users are expected to include keychain sharing capability in their target.

Key chain sharing capability is also needed for firebase_auth on macOS.

I've create an issue on the Flutter repo which may solve the problem: flutter/flutter#121702
