- You don't need to drain W&B or shut it down - W&B will be temporarily unavailable until MySQL comes back - Adjusted verification steps a bit

Pull request overview
Documents the new MySQL baseline for W&B Self-Managed deployments (moving from MySQL 8.0.x to MySQL 8.4.x), adds an end-of-life notice for MySQL 8.0.x, and provides a high-level (W&B-sequence-focused) upgrade guide in the Operator docs.
Changes:
- Update Self-Managed version requirements to recommend/require MySQL 8.4.x and add Aurora versioning guidance.
- Add a reusable “MySQL 8.0 EOL / upgrade to 8.4.x” callout snippet and surface it across key Self-Managed pages.
- Add an “Upgrade MySQL to 8.4.x” section to the Operator guide and update Self-Managed infra requirements wording.
