Code Review
This pull request introduces a release note template for TiDB v8.5.5. The template is well-structured overall. My review includes suggestions to enhance the Improvements and Bug fixes sections by adding component-specific placeholders, making the template more comprehensive and user-friendly for technical writers. I have also included minor formatting suggestions to improve table clarity and ensure the file ends with a newline, adhering to common best practices.
