RafaelMarreca Push Dispatch for Firebase Cloud Messaging

1.0.1

• Renamed plugin to “RafaelMarreca Push Dispatch for Firebase Cloud Messaging” (new slug: rafaelmarreca-push-dispatch) to comply with WordPress.org trademark guidelines.
• Added an “External services” section to the readme documenting the use of Google OAuth2 and Firebase Cloud Messaging, with links to Google’s Terms of Service and Privacy Policy.
• Removed deprecated openssl_free_key() call (PHP 8+ no longer requires it; PHP 7.4 garbage-collects the key at scope exit).
