[m115][omnibox][cr23] Fix pdf test for SS height.

m115 merge.

crrev.com/c/4581107 launched omnibox SS height, increasing the omnibox
height from 28px to 34px.

This decreased the height available for page contents.
`PDFExtensionJSTest.AnnotationsFeatureEnabled` is sensitive to the
height, so it began failing.

This CL adjusts its expectations to pass with the SS height launch. I
think the test is rendering a PDF dialog then measuring the location of
some items. It seems reasonable that the location of things moves when
the available height decreases. I simply updated the expectations to
match the new positions. But I didn't actually verify the correctness of
the new values.
