Android Build Error: Unresolved reference 'currentActivity' in RN 0.81.0 with new arch enabled

[LuuNguyen0811]

Feature request

After upgrading our React-Native version to 0.81.0 android build fails with error:
Function invocation 'getCurrentActivity()' expected.

Why it is needed

For background, React Native deprecated that currentActivity property in 0.80, and removed it in 0.81 (pretty quick turnaround)

Possible implementation

change currentActivity to get from reactApplicationContext.currentActivity

I create a PR for it
