[0.74] Stub com.facebook.react.settings on 0.74

[cortinico]

Summary:

This is a stub of the com.facebook.react.settings plugin.

The plugin got added in 0.75, but to make it easier for 0.74 users to upgrade to 0.75, we're
creating a stub plugin that does nothing. This way, users can include a id("com.facebook.react.settings")
in their settings.gradle file without causing a build failure on 0.74.

This was requested by @gabrieldonadel for Expo templates

Changelog:

[INTERNAL] - Stub com.facebook.react.settings on 0.74
