[docs] AuthSession's useAuthRequest's promptAsync accepts WebBrowser's AuthSessionOpenOptions

[c5-ericlin]

Summary

We can see here and here that the options passed to promptAsync are (possibly augmented with url) and then passed to WebBrowser.openAuthSessionAsync. The docs (and corresponding Typescript types) currently indicate that the only options allowed in promptAsync (promptAsync under useAuthRequest) are AuthRequestPromptOptions, but more options are technically allowed given the code referenced above. The docs and Typescript types should also include the options listed under WebBrowser's AuthSessionOpenOptions as indicated by the docs for openAuthSessionAsync.

Anything else?

The typescript types are incorrect as well.
