fix: update Apple Pay entitlements email address (#59)

* fix: update Apple Pay entitlements email address

The previous email address (apple-pay-provisioning@apple.com) is no longer
valid and bounces. Updated to the correct address (iap_entitlements@apple.com)
as documented on Apple's official In-App Provisioning page.

Also added the required email format (subject line and body content) per
Apple's documentation at https://applepaydemo.apple.com/in-app-provisioning

* fix: add Apple's In-App Provisioning submission form link

Apple now directs issuers to use a formal submission form at
developer.apple.com in addition to the email address.

* fix: note that only Account Holders can access the submission form
