docs: link external symbols from the docs (#530)

Links several interfaces / classes from Crawlee and `apify-client` in
the API reference. Recent updates to
`@apify/docusaurus-typedoc-api-plugin` allow rendering those as links in
the built HTML.

The enumeration is not exhaustive, it's very possible I missed some
interfaces / types.

Closes #283
