I added RNN to an existing project
Error when building the app
'RNReanimated/RETurboModuleProvider.h' file not found

@billel-boudchicha take a look at the 2.0.0-alpha.6 release notes -- these header files and methods have been renamed. For example, RNReanimated/RETurboModuleProvider has been renamed to RNReanimated/REATurboModuleProvider.
Please update the diff to reflect this.
