Change Vertical ScrollView to take Context instead of ReactContext

Summary:
The `ReactScrollView.java` constructor is using `ReactContext` instead of `Context`, which is inconsistent to the horizontal scroll view. This is the result from D3863966 (2cf2fdb) when an OSS issue needs to be addressed. That issue and all call sites to use the `ReactContext` are deprecated now.

Revert this back to use `Context` to be less restrictive.

Changelog:
[Android][Fixed] - Revert `ReactScrollView` to use `Context` instead of `ReactContext` in the constructor to be less restrictive.
