require.getModules()returns empty modules list under react-native 76

[dprevost-LMI]

Description

Since our application has a critical business use case on boot, we had to split code using require to speed up our bundle to load, and that worked really well.
To ensure the expected module loaded stays the same, and our colleague does not start pulling unwanted modules, we have used require.getModules() against some allowed lists to spot any new undesired modules.

However, after upgrading to react-native 0.76.7, require.getModules() returns an empty array list. On react-native 0.75.5, it works well.

On react-native 75 it uses metro v0.80.9.
On react-native 76 it uses metro v0.81.1

I looked at metro issues, and nothing was reported there, so I'm more inclined to believe it is react-native related! Let me know, I can move/open an issue in metro, too, if you think it is more metro-related!

Steps to reproduce

1. Build start any app
2. In the index.js add a line like console.log('require.getModules()',require.getModules())
3. We can observe that it returns an empty list

Below is an example of the loaded module filter on the node_module folder that we would expect to see on 76, but that is empty
