React-native-track-player: Fix the ReadMe.md file

[TheRogue76]

What's the problem?

The Doc is outdated on both the website and the github page. it does not cover A) how autolinking will handle linking on its own on RN Ver >= 0.60 and B) references a (in my experience after two days of debugging) pretty bad package for swiftifying the project while the steps required are much easier (see this thread on stack overflow and this issue).

To Reproduce
yarn add react-native-track-player
yarn add react-native-swift
npx react-native swiftify
npx react-native link

For further clarification, react-native-swift doesn't setup the swift file correctly and it causes pod install to crash with a [Xcodeproj] Consistency issue: no parent for object RNPlaceholder.swift: SourcesBuildPhase, SourcesBuildPhase, SourcesBuildPhase, SourcesBuildPhase error
