[DOCUMENTATION] Update EZID Deployment Schedule Docs

[adambuttrick]

Background

EZID deployments are no longer restricted to the early Thursday AM maintenance window due to load balancing capabilities. The documentation should be updated to reflect this.

Current State

• Documentation does not indicate under what circumstances deployments are restricted to early Thursday AM window (historically true when deployments required complete service downtime)

Actual Practice

• EZID deployments can occur at any time due to the addition of load balancing
• Early morning Thursday window is only used for substantial downtime scenarios (which are now rare)

Requested Changes

1. Review all deployment-related documentation, including in Confluence.
2. Update any references to deployment timing to reflect current practices, including adding a clear statement about:

• Ability to deploy at any time due to load balancing
• Use of early Thursday AM window only for substantial downtime scenarios
• Normal deployment process maintaining service availability
