fix(build): update version + lockfile and ensure correctness in ci

[mrcjkb]

Hey :wave:

I noticed your last release and wanted to package it for nixpkgs. It looks like you forgot to update the version in Cargo.toml + Cargo.lock again.

This PR adds some safety, as discussed in #67, by:

• Extracting the version from the git tag and storing it in the VERSION environment variable.
• Checking that it is set correctly in Cargo.toml (we have to remove the v prefix - will fail if not).
• Ensure the lockfile is up to date (will fail if not).

I've also bumped the version in Cargo.toml to 0.4.3 and updated the lockfile. Would you be open to pushing a 0.4.3 tag, so I can package this for nixpkgs?

Thanks. Haha I thought I had it right this time.

I'll push a 0.4.3 tag

🤔 looks like it broke something?

The nix build workflow should already fail if there is a mismatch, not sure we also need to fail the release for this.

It should fail if the lock file is out of date, but it won't fail if the version in Cargo.toml doesn't match the release tag.
