Fix bump-minor-version to handle version 0.9 correctly

The previous yq expression used floating-point arithmetic to increment
the minor version ((0.9 * 10 + 1) / 10 = 1.0), which produced 1.0
instead of the expected 0.10. Replace with awk-based string splitting
that treats major and minor as separate integers, preserving the
major.minor format across all version numbers.
