* doc/misc/erc.texi (Modules): Recommend using `describe-variable'
instead of `customize-option' because the latter needs the symbol to be
loaded.
* lisp/erc/erc.el (erc-modules): Remove autoload cookie because it
caused customizations for this option to load the main library. This
reverts the thrust of bb894845 "Teach customize-option about
erc-modules", which was added in ERC 5.6 and Emacs 30. The motivation
for the original offending change was to allow new users to run M-x
customize-option RET erc-modules RET immediately after startup instead
of M-x customize-group RET, followed by an I-search. (Bug#73812)
