copy webpage doc code includes "$"

Is your feature request related to a problem? Please describe.
http://pulsar.apache.org/docs/en/security-tls-transport/ click on "copy" includes "$" so I cannot paste and run at once.

Describe the solution you'd like
copy should include only code.

I' d like to. I saw

<code class="language-shell" data-lang="shell" id="code11"><span class="nv no-select">$ </span>crowdin generate</code>

on crowdin' s webpage source. Is there any magic markdown syntax to add $, or we just remove all of $?
