x/tools/go/analysis/passes/printf: revert URL in error message

Revert CL 422854, which added a URL to this one error message,
shortly after the Go 1.19 release, which means there is still time
to keep it from ending up in Go 1.20.

	% go test
	# runtime/metrics_test
	./description_test.go:61:4: (*testing.common).Errorf format %s has arg samples[0].Value.Kind() of wrong type runtime/metrics.ValueKind, see also https://pkg.go.dev/fmt#hdr-Printing

After this CL the ", see also" will not print.

The URL is undoubtedly helpful in some cases, but it makes the
error much longer and reduces the signal-to-noise ratio.
It is also not clear why this one error deserves special treatment.

We should have a general solution for getting users to details
about the specific errors being printed, not URLs in every message.

This reverts commit 88d981e.
