Describe feature

Say we have a workflow that at either the job or steps layer has the following variable declaration:

foo: bar

At the time of writing, passing in an environment variable such as act -j job --env foo=another-value will not overwrite foo, and the value will be bar when the workflow runs in act.

The use case here is that I can overwrite the default behavior of the workflow in some way; such as where the workflow should find config files, for example. This could allow for testing without having to change the actual workflow first.

I came across this when I wanted to change the path to output some TLS certs that my app uses from what my workflow usually does.

Let me know if I missed something and it does actually work; I'm happy to go ahead and make the PR as well.
