ci: replace home-grow cargo semver-checks action

This PR replaces our home-grown `cargo semver-checks` action with the official one: https://github.com/obi1kenobi/cargo-semver-checks-action/issues/47.

This action has support for cargo workspaces and will automatically check all crates that have `publish` set to `true`. This removes a big time component for our CI checks and introduces one that runs in parallel with all others. I hope to reduce the effective CI time through that, plus it means we need to maintain less code.

The official action would download the latest release of cargo-semver-checks. This might result in a non-reproducible CI. To avoid this, we retain the one-line download statement from our home-grown action.

Pull-Request: #3923.
