This reverts commit 7100756.

Please select one of the following

• I am removing an existing difference between facebook/react-native and microsoft/react-native-macos 👍
• I am cherry-picking a change from Facebook's react-native into microsoft/react-native-macos 👍
• I am making a fix / change for the macOS implementation of react-native
• I am making a change required for Microsoft usage of react-native

Summary

There are several places in the react native repo where the version number is hardcoded. On the *-stable branches, the version matches the actual version. On main/master, the version number is set to 1000.0.0 (To make it obvious the tip of the repo is not an official version of RN). At some point in one of our merges, we didn't revert the version number, meaning we were reporting we are still 0.63.3. Coincidentally, I'm pretty sure this is heavily related to why our circle-ci job fails.

Let's fix the version numbers back to 1000.0.0

hey Saad Najmi (@Saadnajmi) now that the main branch has merged back stuff from the 0.66 stable is this still needed? I think that if the answer is yes it'd be great to get it in soon :) I'm sure that a quick rebase then CI should be ✅ and we can 🚢 it :)
