[Doc] Document the removal of compaction

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.

### What issue do you find in Pulsar docs?

There is no documentation about how to remove compaction from a topic

### What is your suggestion?

Add it to the cookbook

### Any reference?

We have a fix to improve this [here](https://github.com/apache/pulsar/pull/21745)

### Are you willing to submit a PR?

- [X] I'm willing to submit a PR!

Review PR #21745 first to understand the documented compaction-removal behavior, then locate the Pulsar cookbook section for topic compaction. Add the missing removal procedure there and verify that the cookbook clearly explains how to remove compaction from a topic.
