Update RN pager view patch file (#6397)

## Summary

Our patch to `react-native-pager-view` for `RN 0.75-rc.6` works, but
seems like it isn't the best way to do that, as stated
[here](callstack/react-native-pager-view#850 (comment)).
In short, removing the `override` keyword will cause tab bar navigation
crashes. Instead, I adjusted the functions' signature, so that they
actually override something.
