Move expect note

This moves the note so that it isn't dangling at the bottom of the
section. I generally would like to avoid these, since it isn't clear if
the note is tied to the previous rule, or the entire section. This seems
to fit with this rule better, anyways.

 The lint expectation is only fulfilled by lint emissions which have been suppressed by the `expect` attribute. If the lint level is modified in the scope with other level attributes like `allow` or `warn`, the lint emission will be handled accordingly and the expectation will remain unfulfilled.
