Dependencies CI check is failing on main #21656

Run cargo machete --with-metadata
Analyzing dependencies of crates in this directory...
cargo-machete found the following unused dependencies in this directory:
datafusion -- ./datafusion/core/Cargo.toml:
	pretty_assertions
Done!

If you believe cargo-machete has detected an unused dependency incorrectly,
you can add the dependency to the list of dependencies to ignore in the
`[package.metadata.cargo-machete]` section of the appropriate Cargo.toml.
For example:

[package.metadata.cargo-machete]
ignored = ["prost"]
