chore: drop 0.71 support from podspec

Summary

Since React Native 0.75 is dropping support soon, I decided to remove this check for 0.71 this makes the podspec a lot cleaner.

Does it affect old architecture? If yes I think we should drop it together with dropping support for old architecture, once new architecture is a bit more stabilized. Normally Bob doesn't drop compatibility unless there's a breaking change that makes it necessary.

Though seems all of that new architecture specific code inside the if condition isn't needed either way so can be dropped.

@satya164 No it doesn't install_modules_dependencies is used for both old and new arch

But isn't that method only available from 0.71? Then the current code does affect both old and new architecture and the change will drop support for old architecture on 0.71 and earlier.
