fix: update outdated Cargo.lock

[nifoc]

Cargo.lock needs to be updated when the version is bumped.

To expand on why not doing this is an issue: I build Rexit using nix and that currently fails because one of the things that nix does it add the --frozen flag to cargo build. That currently results in:

...
       > error: the lock file /build/source/Cargo.lock needs to be updated but --frozen was passed to prevent this
       > If you want to try to generate the lock file without accessing the network, remove the --frozen flag and use --offline instead.

I will merge it now, but wont make a release purely for this change. It will be included in the next one

Thank you!

Just FYI: The next one will need another update to Cargo.lock (because presumably the version will change again)
