Instance jsBundleURLForBundleRoot with fallbackExtension

[JulioCVaz]

Sumary

In react-native 0.70 was updated file RCTBundleURLProvider and removed fallbackResource in jsBundleURLForBundleRoot method instance. The incorrect import cause problems during build with react-native-code-push. Now is need to use fallbackExtension instead fallbackResource.

@JulioCVaz, please resolve the conflicts. The documentation was partly updated, causing conflicts with your changes. Additionally, please remove fallbackExtension as it is not required.

Regarding the DemoApp, I don't think we need to modify the code in it, as it still uses an older version of react-native.

@JulioCVaz Let's remove fallbackExtension:nil part, as it is not needed.

Perfect @DmitriyKirakosyan I think so this PR is not more necessary :)

@JulioCVaz , you’re right. All the code parts with fallbackResource are under RN <0.70 blocks, so we can close this PR. Thanks a lot for your time and effort in contributing!
