[Monorepo] Move catalogd/README.md content to project README

- Integrated relevant content from catalogd/README.md into the project's main README by adding Demo and Quick-Start steps from catalogd/README.md to the main README.
- Removed the old catalogd/README.md as its remaining content (e.g., contribution guidelines) is already covered in CONTRIBUTING.md.

+
+1. To get started with OLM v1, please see our [Getting Started](https://operator-framework.github.io/operator-controller/getting-started/olmv1_getting_started/) documentation.
+
+1. Create a `ClusterCatalog` object that points to the OperatorHub Community catalog by running the following command:
+
+    ```sh
+    $ kubectl apply -f - << EOF
+    apiVersion: olm.operatorframework.io/v1
+    kind: ClusterCatalog
+    metadata:
+      name: operatorhubio
+    spec:
+      source:
+        type: Image
+        image:
+          ref: quay.io/operatorhubio/catalog:latest
+    EOF
+    ```
+
+1. Verify the `ClusterCatalog` object was created successfully by running the following command:
+
+    ```sh
+    $ kubectl describe clustercatalog/operatorhubio
+    ```
+
+   *Example output*
+    ```sh
