wait_for_connection: fix errant warning for local connection(s) (#84421)

This prevents "[WARNING]: Reset is not implemented for this connection" when
using wait_for_connection with localhost or other local hosts.

It's arguable (from a consistency/correctness perspective) that
`ansible.plugins.connection.local.Connection.reset()` should call
`Connection.close()`. I went for a no-op on the basis of "if it aint broke
don't fix it", and erred on the side of keeping existing semantics. However
either option would be fine with me.
