Review Comment:
   Should this part be split into several parts to improve readbility?
   
   eg.
   ```
   #### Proxy
   
   #### Schema
   
   #### Tiered storage
   
   ...
   ```

Review Comment:
   @Technoboy- can we add website updates as below? 
   (These improvements are related to both doc and website, but more related to the website, workflow, and overall content experience, so I categorize them as "website")
   
   
   ```
   ### Website
   
   - [feat][website] language support is added for pulsar-admin function flags [#16853](https://github.com/apache/pulsar/pull/16853)
   - [feat][website] line number is shown in code blocks [#75](https://github.com/apache/pulsar-site/pull/75)
   - [feat][website] announcement bar is shown on Pulsar main page [#76](https://github.com/apache/pulsar-site/pull/76)
   - [feat][website] badges are shown in README [#16233](https://github.com/apache/pulsar/pull/16233)
   - [feat][website] tabs can be synced [#15812](https://github.com/apache/pulsar/pull/15812)
   - [improve][website] tabs are highlighted [#134](https://github.com/apache/pulsar-site/pull/134)
   - [fix][website] language highlights can work consistently [#15919](https://github.com/apache/pulsar/pull/15919)
   - [fix][website] toc are highlighted correctly when scrolling [#137](https://github.com/apache/pulsar-site/pull/137)
   ```
   
   @SignorMercurio do I miss anything?
   I do not add "automate configuration doc task" since it's WIP
