Subject: [PATCH] Update libcnb.rs to 0.32.0

Updates all of the libcnb.rs crates (including the transitive
`libcnb-*` crates) to the latest release, which includes OpenTelemetry
crate upgrades, and switches `libherokubuildpack`'s `tar` module to the
faster `zlib-rs` backend for decompression.

This is being done manually (well, via an LLM) rather than via
Dependabot, since Dependabot doesn't update the transitive libcnb.rs
crates correctly, and its default 3 day cooldown would delay the
update.

See:
https://github.com/heroku/libcnb.rs/releases/tag/v0.32.0
https://github.com/heroku/libcnb.rs/compare/v0.31.1...v0.32.0
