fix: publishing crates with correct versions

[ielashi]

Problem

When publishing canbench previously, I had to manually change the local dependencies to point to the versions in cargo (e.g. when publishing canbench-rs, I need to change the dependency on canbench-rs-macros from the local folder to the new version of canbench-rs-macros that I just published). This process is messy and confusing, and is one of the things that wouldn't be intuitive to anyone publishing canbench in the future.

Solution

Update Cargo.toml such that, locally, it uses a folder, and when publishing, it uses a specific version. That way, publishing can be seamless and requires no local modifications moving forward.
