Remove requirements for proto comments from CODING_STANDARDS

They've been made obsolete by .stub.php files and are often
outdated as they're not the source of truth.

-The `proto` keyword there is just a helper for the `doc/genfuncsummary` script

-Optional arguments are written like this:

-```c
-/* {{{ proto object imap_header(int stream_id, int msg_no [, int from_length [, int subject_length [, string default_host]]])
