Warnings from react-native & @react-native/codegen about missing Peer Dependencies

[fbartho]

Description

Using yarn 3.6.4 (berry) on a new react-native project, I get the following dependency warnings:

$ yarn
➤ YN0000: ┌ Resolution step
➤ YN0002: │ @react-native/babel-plugin-codegen@npm:0.76.6 doesn't provide @babel/preset-env (pda3fc), requested by @react-native/codegen
➤ YN0002: │ babel-plugin-transform-flow-enums@npm:0.0.2 doesn't provide @babel/core (pd2efd), requested by @babel/plugin-syntax-flow
➤ YN0002: │ react-native@npm:0.76.6 [24bb2] doesn't provide @babel/core (p230be), requested by babel-jest
➤ YN0002: │ react-native@npm:0.76.6 [24bb2] doesn't provide @babel/preset-env (pe8640), requested by @react-native/codegen
➤ YN0000: │ Some peer dependencies are incorrectly met; run yarn explain peer-requirements <hash> for details, where <hash> is the six-letter p-prefixed code

Of these, it appears babel-plugin-transform-flow-enums isn't provided by this repository, but the rest of them are.
