feat: allow sorting of Actors collection (#422)

Added new sorting param sortBy for the new feature described in this
[Issue](https://app.zenhub.com/workspaces/platform-team-5f6454160d9f82000fa6733f/issues/gh/apify/apify-core/20997)

I will wait until [Apify-Core
PR](apify/apify-core#21566) is deployed and then
will merge this.



One note, I am not sure if I added the sortBy parameter correctly.
Example code below:
`return await self._list(my=my, limit=limit, offset=offset, desc=desc,
sortBy=sort_by)`
I tried to follow similar examples with a camel case api parameter.
Please let me know if this is not the correct syntax.
