URL: https://github.com/apache/pulsar/issues/17384

   ### 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?

   If I click the copy button, `\n` was copied as well, which is inconvenient 
to change args and may run commands unexpectedly because of the tailing `\n`:

   ### What is your suggestion?
   
   Trim all redundant newlines of code blocks like this:
