Update RN pager view patch file

[szydlovsky]

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. In short, removing the override keyword will cause tab bar navigation crashes. Instead, I adjusted the functions' signature, so that they actually override something.

It is better to go with this fix.

@Romick2005 yeah, I use exactly that fix (brought back override, removed nullability of child arguments)
