update pagerduty_alert step.yaml

[ghost]

Removed the default value for the assignee as it is not needed if there is an escalation policy

[ghost]

@lrochette I have updated the steps.yaml. Updated the version and remove the default value for ASSIGNEE_USER_ID. let me know if there is anything else needed.

I understand the change based on the previous PR but I'm afraid it could break stuff for people who rely on that default value

This change is because there is an IF statement for ASSIGNEE_USER_ID. Why is the need for this if statement if we are passing in default values and it is not required? Also, you cannot use an escalation policy with this default value present.

Also, you cannot use False in the codefresh.yaml to disable this or not have a value for ASSIGNEE_USER_ID.

Please provide a better workaround @lrochette if you have one.
