Bump AGP to 7.4.x

[cortinico]

Summary:
Fixes#35439

There is a bug in AGP 7.3.x which is causing assets to don't be copied properly inside the
final artifact: issuetracker.google.com/issues/237421684
As AGP 7.4.x is really close to release (is in Beta5, should be released stable in the next weeks)
we should be fine by bumping to beta5.

This also requires a bump of RNGP

Changelog:
[Android] [Changed] - Bump AGP to 7.4.x
