Create a new guide for scaling the crawlers

[vdusek]

• We could create a new documentation guide for scaling the crawlers (mainly the features from _autoscaling subpackage).
• The guide should include the following:
  • ConcurrencySettings - how users can configure the concurrency of requests.
  • Add a short explanation of the internal components:
    • Snapshotter,
    • AutoscaledPool.
• Inspiration: https://crawlee.dev/docs/guides/scaling-crawlers
• How to name it? I used "request scaling" here, but it is not precise enough.

why a different name? also, you scale the crawler to be able to run more requests, you don't scale the requests, right?

i would rather have a python version of the very same page instead of a different page

Yeah... I created the issue at first without looking into JS Crawlee docs, then updated it with the inspiration bullet, but not updating the title & description. I will use the same naming.
