fix(router): accept options function

[vilnytskyi]

Why

TypeScript is currently prohibiting usage of options prop as a function, to configure options depending on route instance. Note that it's solely typing issue, the library itself supports it (see useScreens.tsx)

How

Adjusted type according to original @react-navigation/core types

Test Plan

Verified that typing works correctly when passing both object & function props.
