blue-green-deploy task doesn't work for deployments not in the same namespace

[makeittotop]

Expected Behavior

The blue-green-deploy task should be passed the namespace as a param alongside other params., so that it could run an operation in that namespace.

Actual Behavior

Currently the task assumes the deployment lives in the same namespace as the pipeline is run from.

Steps to Reproduce the Problem

1. Pass in a deployment manifest yaml to the task which has workload in a namespace other than the current one.
2. The task will assume that the deployment is in the same namespace , and will start querying for that deployment blocking indefintely. https://github.com/tektoncd/catalog/blob/main/task/blue-green-deploy/0.1/blue-green-deploy.yaml#L82
