Add baking time job to release-tools

What does this MR do?

Includes two new jobs:

• One to wait for the canary deployment
• One to canary baking time.

Canary baking time has the same behavior as the original in the deployer pipeline:

• Triggers production checks to validate if a deployment to production can be authorized.
• It runs after 60 minutes and only if the canary deployment has been completed
