feat: allow sorting of Actors collection

[protoss70]

Added new sorting param sortBy for the new feature described in this Issue

I will wait until Apify-Core PR is deployed and then will merge this.

lgtm, just one note about the PR title (which applies to all the repositories, especially libraries), we follow conventional commits, so it should be in the form feat: ... where the ... will end up in the generated changelog - that part should be imperative and should describe what changed so users can understand it. Only feat/fix/perf commit types will end up in the changelog (plus any PR with states a breaking change in the PR description).

For this PR, I would go with something like feat: allow sorting of Actors collection or similar (I changed it already but feel free to improve it). The same applies to fixes, the commit type prefix is not part of this "sentence", so while it might look weird at first, using something like fix: fix this and that is the correct way, while fix: this and that is not.
