### Describe the bug

When configuring OAuth/Cognito Hosted UI using the `amplify auth add` command, the CLI generated a domain for the Hosted UI resource. The full domain will typically look something like this:
```https://-.auth.us-west-2.amazoncognito.com```

It appears that this domain violates a character count limitation set by Apple, when integrating Hosted UI with Sign In With Apple:

From [this](https://developer.apple.com/forums/thread/122536) Apple forums thread:

```terminal
We were able to fix this issue with the following steps:

Add domain/subdomain and return URL to your Apple account
Check the length of the domain in redirect_uri it shouldn't be too long
In our case, domain length was 54 symbols and it start working when we reduce it to 49 symbols. It looks like there is a limit to the domain name length of around 50 symbols.

It was easy to reach this limit since we use a Cognito domain with a prefix and prefix attached to quite long domain name ".auth.eu-central-1.amazoncognito.com".
```

I have reproduced this issue by using the domain set by the CLI, which causes the `Invalid redirect_uri` error on the Sign In With Apple UI. After manually modifying the domain length in Cognito console and in my amplify config, Sign In With Apple works correctly.

### Expected behavior

The CLI should create a domain that can be consumed by all identity providers that are supported out of the box by Cognito.

### Reproduction steps

1. Init an amplify project and add auth, choosing the OAuth option. Add Sign In With Apple.
2. Follow all instructions for SIWA from the [Amplify docs](https://docs.amplify.aws/lib/auth/social/q/platform/react-native/).
3. Attempt to login.
4. Note the redirect_uri error.
5. Change the domain in Cognito and in the amplify config, to something random/unique but very short.
6. Attempt to login. It should be successful.

### Additional information

_No response_

Start with the auth flow behind `amplify auth add` and the generated Hosted UI domain, then compare the value stored in the Amplify config with the Cognito domain shown in the console. Reproduce the Sign In with Apple `Invalid redirect_uri` error using the listed steps. Done means a generated domain stays within Apple's apparent length limit while remaining unique and usable by supported Cognito identity providers.
