fix(ci): install libclang before publishing crates in the release job (#10941)

rocksdb 0.24 made librocksdb-sys always run bindgen, which needs libclang
at build time. cargo publish's verification build compiles from a clean
checkout with no cache, so it hit this on zebra-state (and would recur on
zebra-consensus, zebra-rpc, and zebrad, which all depend on zebra-state).
