Fix T81901: Use the 2.90 scrape brush preset as default

The new preset I made for 2.91 is way more controllable with lower
strength values and does not have the accumulate bug, but until the
brush management is in place to ship multiple versions of the brush,
probably most people expect something closer to the old version to be
the default.
