The -user flag was previously undocumented in the 'erl' command reference. This flag allows users to override the default 'user' process (the I/O server) during the boot sequence. This commit adds the flag description and includes a warning regarding the I/O protocol requirements when replacing the default handler, as standard 'io' module calls will fail if the custom module does not implement the expected interface.

Just a thought, might be easier just to build the docs for docs only changes, saves running all the other github runners. |
Turn note into warning because it has warning css in the html site.
