bug#74759: 30.0.92; Gnus configuration warning

[Anush V]

Hello maintainers,

I tried executing the sample gnus configuration from [[info:gnus#Search
Engines][gnus#Search Engines]] in emacs with ~--no-init~ option, and I'm getting
a warning.  This code snippets works as expected, though.

Steps to reproduce:

emacs -Q
M-x ielm

executed this code

       (setopt gnus-select-method
       '(nnmaildir "My Mail"
               (directory "/home/user/.mail")
               (gnus-search-engine gnus-search-notmuch
                                   (config-file
       "/home/user/.mail/.notmuch_config"))))


I get this warning

  ■  Warning (emacs): Value ‘(nnmaildir "My Mail" (directory 
"/home/user/.mail") (gnus-search-engine gnus-search-notmuch (config-file 
"/home/user/.mail/.notmuch_config")))’ does not match type gnus-select-method


I’m wondering if this is a bug, or if Im doing something wrong.

Thank you for your time.
