Always use wasm executor in container collators

[tmpolaczyk]

We use a NativeElseWasmExecutor for all chains, but collators don't have the container chain's native runtime. So their executor was trying to use the native dancebox runtime as the container chain runtime, which fortunately resulted in a version mismatch and the wasm container chain runtime was always used.

This can be verified by starting zombienet with export RUST_LOG=info,executor=trace:

2024-02-13 18:33:48.286 TRACE tokio-runtime-worker executor: [Container-2000] Request for native execution failed native=dancebox-500 (dancebox-0.tx1.au1) chain=container-chain-template-500 (container-chain-template-0.tx1.au1)

As a bonus we now have two types of clients, Arc<ContainerChainClient> and Arc<ParachainClient>, and using one client in place of the other results in a compile error.
