The idea is to make fscheckpoints be forward compatible (newer runsc versions will successfully read fscheckpoints generated by an older runsc). The exact details of how this plays out will obviously depend on ongoing runsc runsc development (for how long to keep work-arounds for breaking changes, etc). While this CL does enable forward compatible fscheckpoints by eliminating the hard-matching requirement on runsc-version, please don't rely on it just yet. PiperOrigin-RevId: 962306264
