[Feature Request] Add a hook to customize "wait_for_load_state" behavior

[moonk-banksalad]

Is your feature request related to a problem? Please describe.
Hello, I am trying to scrap a SPA page where "domcontentloaded" or "networkidle" event does not guarantee content readiness.

Describe the solution you'd like
One solution would be adding a way to pass a hook function which gets called right after opening a web page and before getting content (https://github.com/ScrapeGraphAI/Scrapegraph-ai/blob/main/scrapegraphai/docloaders/chromium.py#L88). If the playwright.Page is passed to this hook, a caller can customize how to determine readiness of the page content.

Describe alternatives you've considered
I am currently trying to workaround this limitation by monkey patching playwright functions.

Additional context
N/A
