Split update-version.sh into two scripts

- scripts/update-version.sh — updates source files (module.prop, Cargo.toml, etc.)
- scripts/update-json.sh — generates Magisk/KSU update-json files

update-json must be committed AFTER the release is published to avoid
a race where Magisk sees a new version but the zip doesn't exist yet.
