Async IPooledObjectPolicy<T>

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Is your feature request related to a problem? Please describe the problem.

I'm trying to create an IPooledObjectPolicy where IBrowser is from Playwright.net. However, Playwright's method to create an IBroswer is `LaunchBrowserAsync`.

### Describe the solution you'd like

An async ObjectPool stack would be nice.

I'm guessing the viral nature of async makes this a more complex feature request?
