Summary

This is a lockfile-only bump of zlib-rs (the backend Vector selects for flate2) from 0.6.0 to 0.6.6. No new dependencies are introduced.

zlib-rs 0.6.4 fixed an aarch64 checksum bug in Adler-32 that could make valid deflate payloads look corrupted on arm64, which is the decode path Vector uses for zlib-format content-encoding in HTTP-based sources. We're pulling in 0.6.6 instead of 0.6.4 since 0.6.4 itself briefly broke the aarch64 build (fixed in 0.6.5). Found this while investigating #25796.

A fix-type changelog fragment is included so arm64 users can find this in the release notes.
