Documentation for `seq-contains-p` is outdated

Hi,

When looking up the documentation for `seq-contains-p` it seems
outdated.

M-x elisp-index-search RET seq-contains-p RET returns:

-- Function: seq-contains-p sequence elt &optional function
    This function returns non-‘nil’ if at least one element in SEQUENCE
    is equal to ELT.  If the optional argument FUNCTION is non-‘nil’,
    it is a function of two arguments to use instead of the default
    ‘equal’.

         (seq-contains '(symbol1 symbol2) 'symbol1)
         ⇒ symbol1
         (seq-contains '(symbol1 symbol2) 'symbol3)
         ⇒ nil

The title is correct but the information shown is for the obsolete
`seq-contains` function.

Best regards,
