OAuth flow could use secrets prompt for AppID & AppSecrets

**Describe the bug**

currently when we prompt for secrets, we display them:


**Amplify CLI Version**
You can use `amplify -v` to check the amplify cli version on your system

v 4.28

**To Reproduce**

`amplify add auth`

**Expected behavior**

show `******` or blank for secrets. this is a built in feature to inquirer/enquirer that we dont use because of the way we set it up in https://github.com/aws-amplify/amplify-cli/blob/4e5f5c62287252ff59ecda050390e9b3c2b00146/packages/amplify-category-auth/src/provider-utils/supported-services.ts. however it should just take a couple small tweaks to do.

**note**

we should scan thru the rest of the cli for other incidences of this pattern
