Add Webhooks API + slim README to docs.mifiel.com

And taught it when to ring.
The README mapped the setup path,
While PHP gained a spring.
Tests and docs now hop in step.}

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Use the package’s published major version.

composer.json declares version 4.0.0, but this example requires ^3.0. Composer cannot select 4.0.0 for that constraint, so copied guidance can install only a 3.x release or fail if none is available. Change the requirement to ^4.0.

Proposed fix

-    "mifiel/api-client": "^3.0"
+    "mifiel/api-client": "^4.0"
