fix: Drop pricing_infos from CreateActorRequest and clarify apify_margin_percentage docs (#1031)

- Regenerates the Pydantic models, TypedDicts, and literal aliases from
the [published OpenAPI
specification](https://docs.apify.com/api/openapi.json), and records its
version in `pyproject.toml`.
- Specification version: `v2-2026-08-24T085852Z` - **unchanged**, which
doesn't rule out a specification change: the published stamp can lag its
content by a deploy. Only the diff tells.
