Remote Config upgrade guide

• Do not upgrade this package if you're using Unity Editor 2018 LTS or Tech Stream 2019. Versions below 2019.4 (LTS) are not supported.

• There's a new initialization for Unity Game Services which will require code updates for those who already implemented Remote Config in their Unity Project. Please review the Initialization section of CodeIntegration for the new code to be added to your implementation.

• Upgrading a project from Unity 2018 or pre LTS 2019; developers no longer need to set the Scripting Runtime in the Editor. The option to change the Scripting Runtime version was removed after Unity 2019.2 https://docs.unity.cn/Manual/UpgradeGuide2019LTS.html#NET

• The latest information on the Service features can be found in the REST API documentation
