Update logged-out A/A test name and re-add logged-in A/A test

[jaclync]

Closes: #8235

Description

Since we had an attempted fix for the previous A/A tests where there is a bias toward the control variant, I created another pair of A/A tests (logged-in/logged-out) so that we can see if the bias issue is fixed.

A note on the experiment name: woocommerceios_explat_aa_test_logged_out_202212 and woocommerceios_explat_aa_test_logged_in_202212 experiment names were already taken by @selanthiraiyan's previous PRs that were closed. I re-cloned the experiments with *_v2 names since we can't reuse the same experiment name.

Testing instructions

Prerequisite: a sandbox is required for testing manual assignments on A/B experiments, you can request one if you don't have one - it'd be useful for testing IAP later as well.

There are no visual differences for the A/A tests, you can test it by setting a breakpoint in the logged-out and logged-in state.

Logged-out state

Prerequisites:

• Please follow the setup in PCYsg-Fq7-p2#assignments-api for proxied sandboxed API requests: connect to sandbox via ssh, and point WP.com API to the sandbox IP address (ifconfig) in the local matchine's /etc/hosts
• The you need to make an authenticated WPCOM request to manually assign the variant
• Find the anon ID of the device by setting a breakpoint in ExPlatService on the line urlComponents.queryItems?.append(URLQueryItem.init(name: "anon_id", value: anonId)) and launching the app
• Make an API request PATCH /wpcom/v2/experiments/0.1.0/assignments with the following body and make sure it's successful:

{
    "variations": {
        "woocommerceios_explat_aa_test_logged_out_202212_v2": "treatment"
    },
    "anon_id": "{{anon_id}}",
    "username_override": ""
}

• In code, set a breakpoint at a logged-out action callback like StoreCreationCoordinator.start
• Launch the app
• Log out of the app or skip login onboarding if needed
• Tap on Get Started or any other actions that trigger the breakpoint set in the first step. When the breakpoint is hit, check the A/A test variant by po ABTest.aaTestLoggedOut.variation in the debug console --> it should say treatment: nil

Logged-in state

Prerequisites:

• Make an API request PATCH /wpcom/v2/experiments/0.1.0/assignments with the following body and the bearer token for the wpcom account (I'd use an A8C account in this case), make sure it's successful:

{
    "variations": {
        "woocommerceios_explat_aa_test_logged_in_202212_v2": "treatment"
    }
}

• In code, set a breakpoint at a logged-in action callback like in HubMenu when an element is tapped
• Launch the app
• Log in to a store
• Go to the Menu tab, and tap on any element in the menu. Or any other actions that trigger the breakpoint set in the first step. When the breakpoint is hit, check the A/A test variant by po ABTest.aaTestLoggedIn.variation in the debug console --> it should say treatment: nil

• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.
