[docs] Provide a generator to generate configuration files automatically

[Jennifer88huang-zz]

Describe the bug
When parameters in the broker.conf, standalone.conf and other configuration files are updated in the code, the docs are not updated synchronously on the Pulsar configuration page . And then we have to check those PRs one by one and add those parameters in the md file. Take #6047 as an example.

Expected behavior
The doc content on the Pulsar configuration page is updated synchronously with code update.

Additional context
We need a generator to generate the configuration files automatically.

@tuteng Could you share how to implement the auto generator tool? Thank you.

Duplicated with #10041. I'll close this issue since we've tracked the status in #10041.
