Description

Helps to reduce number of dependencies by removing duplicated ones.

Hi, and thanks for your interest! As we use dependabot to submit PR's with updates for the dependencies I don't think this is worth it. If we downgrade tempfile dependabot will submit a PR trying to update it afaik, trying to keep track of downgraded packages and keeping ignoring upgrades for certain so that we have less package versions on Cargo.lock is therefore not worth it imho.

Only the 2nd commit downgrades a dependency as pointed out at https://github.com/libp2p/rust-libp2p/pull/5318#discussion_r1568777634. I will revert that commit since the repo has dependabot integration.
