Bug 1992739 [wpt PR 55245] - [anchor] Update position-area-scrolling-{001,003} tests., a=testonly

Automatic update from web-platform-tests
[anchor] Update position-area-scrolling-{001,003} tests.

These tests were written before the "scrollable containing block" was
present in the spec. Update them such they assert the new sizes.

As the sizes are expected to remain static now, simplify them as well
just testing a few core cases.
