KAFKA-16894: share.version becomes stable feature for preview (#19831) 

This PR sets `SV_1` as the latest-production share version. This means
for AK 4.1 it will be a preview feature, not enabled by default, but can
be enabled without turning on unstable features. This is analogous to
how ELR worked for AK 4.0.
