Do not set the default network to host (#55)

In [nektos/act/pull/1739](https://github.com/nektos/act/pull/1739), the container network mode defaults to `host` if the network option isn't specified in `options`.  When calling `ConnectToNetwork`, the `host` network mode may cause the error:
`Error response from daemon: container sharing network namespace with another container or host cannot be connected to any other network`
see the code: a94a01bff2/pkg/container/docker_run.go (L51-L68)

To avoid the error, this logic needs to be removed to keep the default network mode as `bridge`.
