Cocoapods: Fix deprecated/removed File.exists method

[iBotPeaches]

Noticed on accident when I upgraded Ruby on accident to 3 - that my pod install failed with:

[!] Invalid `Podfile` file: 
[!] Invalid `RNReanimated.podspec` file: undefined method `exists?' for File:Class.

 #  from /Users/xx/iOSProjects/xx-app/node_modules/react-native-reanimated/RNReanimated.podspec:5
 #  -------------------------------------------
 #  reanimated_package_json = JSON.parse(File.read(File.join(__dir__, "package.json")))
 >  config = find_config()

Theres a good deal of other errors after I fixed this one on other projects, but this looks like a safe change to get ahead of the future Ruby upgrade. Yeah I did downgrade back to 2.7.5.

Summary

Resolves the removed method of File.exists in Ruby3. The alternative method of File.exist is recommended and already exists on 2.5 for no breaking changes.

Test plan

A local working pod install

Thanks for your PR! 🚀

I'm getting this error too. But I don't understand how I can fix it with this, can you explain?

I thought my explanation was pretty detailed - what part are you lost on?

go to:
Project/node_modules/react-native-reanimated/scripts/reanimated_utils.rb
and change File.exists for File.exist

Is this being released?
