docs: Improve API doc groups (#509)

### Description

- Improve API doc groups (as was done in
apify/crawlee-python#1309).
- `Actor` and `ChargingManager` class docstrings were updated.
- Missing symbols from Crawlee were exposed here.
- Usage of `ignore_docs` was removed, as it's no longer needed.

+    Actors are serverless programs running in the cloud that can perform anything from simple actions
+    (such as filling out a web form or sending an email) to complex operations (such as crawling an
+    entire website or removing duplicates from a large dataset). They are packaged as Docker containers
+    which accept well-defined JSON input, perform an action, and optionally produce well-defined output.
