Include pre-releases in >=2.3.0 comparison. Fixes #4080.

This is a change to the >=2.3.0 comparison. Without this change, such a
comparison will exclude pre-release versions.

The rationale is that this makes the comparison more consistent with
<2.3.0 (which excludes all pre-releases) and ~2.3.0 (which includes
pre-releases).
