[Console] Added documentation about command profiling

I just noticed the new `--profile` option wasn't documented (only on [this blog post](https://symfony.com/blog/new-in-symfony-6-4-command-profiler)) yet, so here's a PR with just some minimal info added to the console page.

+Profiling Commands
+------------------
+
+When debug mode and the profiler are enabled, you can run a command with the
+``--profile`` option. Symfony will then collect data about the command execution.
+When the execution is over, the profile is accessible through the web page of
+the :doc:`Symfony Profiler </profiler>`.
+
+.. tip::
+
+        If you run the command in verbose mode (``-v``), Symfony will display
+        in the output a clickable link to the command profile (if your terminal
+        supports links). If you run it in debug verbosity (``-vvv``) you'll
+        also see the time and memory consumed by the command.
