fix: pass all props to custom headerLeft

[vonovak]

I'm having an issue with a custom back button in v6: I'm passing a react component as headerLeft and I'm expecting it to receive some props such as onPress (see v5.

react-navigation/packages/stack/src/views/Header/HeaderSegment.tsx

Line 296 in 89d3365

onPress: onGoBack,

) but in v6, these props are no longer passed, they are only passed to the default back button (

react-navigation/packages/stack/src/views/Header/HeaderSegment.tsx

Line 161 in b013057

onPress={onGoBack}

).
This PR fixes it.

test plan: use the following diff in the example app. Currently, the button does not react to presses. With the fix, it works as expected (takes user to previous screen).
