bug#45673: 28.0.50; Fix gnus-score-find-score-files-function example

[David Edmondson <dme@dme.org>]

The example provided in the gnus manual on how to use a list of
functions as the value for gnus-score-find-score-files-function is
incorrect and results in an error when used:

Debugger entered--Lisp error: (invalid-function "all.SCORE")
  ("all.SCORE")
  (lambda (group) ("all.SCORE"))("nntp+gmane:gmane.linux.kernel")
  gnus-all-score-files()
  gnus-possibly-score-headers()
  gnus-summary-read-group-1("nntp+gmane:gmane.linux.kernel" nil t nil nil nil)
  gnus-summary-read-group("nntp+gmane:gmane.linux.kernel" nil t nil nil nil nil)
  gnus-group-read-group(nil t)
  gnus-group-select-group(nil)
  gnus-topic-select-group(nil)
  funcall-interactively(gnus-topic-select-group nil)
  call-interactively(gnus-topic-select-group nil nil)
  command-execute(gnus-topic-select-group)

A patch to fix the example in the documentation follows.
