bug#67007: 29.1.90; treesit-simple-indent-presets example on match

[Maxim Kim]

While trying to play with treesit indent rules I came across
`treesit-simple-indent-presets' where I believe example given is wrong:

C-x o treesit-simple-indent-presets RET
----
(match NODE-TYPE PARENT-TYPE NODE-FIELD NODE-INDEX-MIN NODE-INDEX-MAX)

    NODE-TYPE checks for NODE’s type, PARENT-TYPE checks for
    PARENT’s type, NODE-FIELD checks for the field name of NODE
    in PARENT, NODE-INDEX-MIN and NODE-INDEX-MAX check for
    NODE’s index in PARENT.  Therefore, to match the first child
    where PARENT is "argument_list", use

        (match nil "argument_list" nil nil 0 0).
----

(match NODE-TYPE PARENT-TYPE     NODE-FIELD NODE-INDEX-MIN NODE-INDEX-MAX)
(match nil       "argument_list" nil        nil            0               0).

5 args in signature vs 6 in example.

Good catch. I fixed it on emacs-29. Thank you!
