[Request]: Clarify usage of official Notarization package deployments in documentation

### Feature description

Clarify in the Notarization documentation that integrators must use the officially deployed Notarization packages and do not need to redeploy them themselves. Include clear references to the official deployments across networks.

### Motivation

Some integrators currently assume they need to redeploy the Notarization packages.

### Requirements

1. Explicitly state in the documentation that redeploying Notarization packages is not required and not recommended.
2. Provide direct links to the official Notarization package deployments on testnet, devnet, and mainnet.
3. Explain why using the official deployments is required for verifiability and trust.
4. Surface this guidance in all relevant documentation sections where deployment or integration steps are described.

### Open questions

- Where are the best places in the documentation to reinforce this message to avoid future confusion?
- Do we want a single canonical page for official deployments that other docs can reference?

### Are you planning to do it yourself in a pull request?

No
