Code Review
This pull request updates the Flashduty alert subscription documentation to include instructions for TiDB Cloud Essential clusters. The changes are well-structured, separating instructions for Dedicated and Essential tiers. My review includes a correction for a broken link and a minor stylistic suggestion to improve conciseness, adhering to the repository's style guide.

| | The Request Unit/s exceeded 80% of Max RCU | Suggested actions: <ol><li>Check your traffic pattern in the RU metrics to determine if it is a gradual increase or a sharp spike.</li><li>If it is a gradual increase, verify if Query Duration has increased. If yes, your current max RCU configuration is likely insufficient.</li><li>Scale up your capacity by manually increasing the max RCU in the TiDB Cloud console to meet demand.</li></ol><br/>If the problem cannot be fixed by your side, contact [TiDB Cloud Support](/tidb-cloud/tidb-cloud-support.md) for further assistance.| | ||
| | QPS suddenly dropped by 80% | Suggested actions:<ol><li>Check if it's caused by increasing query latency.</li><li>Check if your application is healthy. If this drop is intentional, ignore this alert. If this drop is not intentional and you cannot identify the root cause, contact [TiDB Cloud Support](/tidb-cloud/tidb-cloud-support.md) immediately.</li></ol>| | ||
