Document Xcode's interactions with push

[tomczoink]

We need to document how to resolve debug issues for Xcode with Push, this includes:

• Creating a support article
• Writing up information for relevant docs
• Dashboard interfaces need useful info

Notes:

Check if the app has Push Notifications well configured in the Apple Developer account:

Go to the target settings > Capabilities > Push Notifications and check if all steps are ok:

Check if the correct certificate is in place in Ably Dashboard.

In Xcode, you can't use production certificate in debug/development.

From oficial documentation:

Xcode sets the value of the entitlement based on your app's current provisioning profile. For example, if you're using a development provisioning profile, Xcode sets the value to development. https://developer.apple.com/documentation/bundleresources/entitlements/aps-environment?language=objc
The easiest way to test production notifications (without releasing the build) is installing the app via TestFlight. Just archive and upload a build and enable internal testing after the build has finished processing in AppStore Connect. Then just install that build in your device.
