Extract `GotScrapingHttpClient` to a separate package and replace with `FetchHttpClient`

[barjin]

Currently got-scraping is a direct dependency of @crawlee/core. Extracting the GotScrapingHttpClient to a separate package (similar to @crawlee/impit-client) and replacing it with a simple fetch-based BaseHttpClient implementation would help with reducing the dependency tree size. The fetch-based client could further serve as a reference HttpClient implementation.
