Update Wasmtime to 2.0.0

Should just be a routine update, nothing fancy going on here.

cd cli/tests/trap-test && cargo --locked test fatal_error_traps -- --nocapture
    Updating crates.io index
error: the lock file /home/runner/work/Viceroy/Viceroy/cli/tests/trap-test/Cargo.lock needs to be updated but --locked was passed to prevent this

@alexcrichton would you mind running make generate-lockfile? one of the test suite's fixtures has a lockfile that fell through the cracks

[alexcrichton]

Indeed, can do!

thank you, as always @alexcrichton 🙏
