 As seen in https://core.trac.wordpress.org/ticket/43941#comment:71, the
 formatting of code blocks looks broken:

  Take the following example
  ```
         register_meta('post', 'my_meta', [
                 'object_subtype' => 'post',
                 'single' => false,
                 'show_in_rest' => [
                         ...
                 ],
                 'type' => 'array',
                 'default' => array(233),
         ]);
  ```

 The GitHub syntax:
 {{{
 ```
 ```
 }}}
 should be converted to the syntax that Trac recognizes:
 {{{
 {{{
 }}}
 }}}
