* lisp/erc/erc-services.el: Fix shape of option in commentary example.
Existing value didn't pass `setopt' validation and raised an error
during successful lookup in `erc-nickserv-get-password'.
(erc-nickserv-passwords, erc-nickserv-identify-autodetect): Update doc
string by removing erroneous constraint, which was no longer applicable
following c6eb114a42 "ERC: NickServ:
Prompt for password last, overall simplifications (bug#46777)".
(erc-nickserv-identify): Simplify doc and guarantee t as return value on
success rather than rely on unadvertised behavior from other API
functions.
