"last 2 versions" seems overly aggressive for Safari versions

[smackfu]

Using "last 2 versions" only includes Safari 17.1 and 17.2. This excludes a bunch of older Safari versions that still have decent usage percentages. For instance, iOS Safari 16.6-16.7 has 2.3 % overall usage as of this writing. These are generally just people who haven't updated to the latest OS version, because of the way Apple ties the Safari and OS version together.

It might be better to just switch to the "defaults" query which is:

> 0.5%, last 2 versions, Firefox ESR, not dead
