discussion: should we adopt the `Cargo-minimal.lock` and `Cargo-recent.lock` approach ?

Describe the enhancement

As mentioned in https://github.com/payjoin/rust-payjoin/issues/337, it's way clearer having a Cargo.lock file than having the pinned dependencies only on the README and CI.

In rust-bitcoin it follows a different approach that might be helpful and clearer, opening this issue for start a discussion about it.

Use case

Adds Cargo-minimal.lock and Cargo-recent.lock files for clearer pinned dependencies and MSRV support.
