Bump Zlib Rs Aarch64 Checksum.Fix

Updated the zlib backend (zlib-rs) from 0.6.0 to 0.6.6, pulling in an upstream fix for an aarch64 NEON Adler-32 bug that could produce incorrect checksums. On arm64, valid zlib-format (RFC 1950) payloads, such as deflate content-encoding handled by HTTP-based sources, could previously be rejected as corrupt with an incorrect data check error.
