Add ZSH config for setting environment variables on macOS Catalina and newer

[GitToTheHub]

On macOS Catalina and newer, Apple switched from Bash to ZSH. The new file for ".bash_profile" is ".zprofile".

Also the AnroidSDK path is different on a current macOS with the latest Android Studio, but I don't know since when this was changed, or if it was always like this.

Platforms affected

Android on macOS

Motivation and Context

Environment variables on newer macOS system must stored on .zprofile instead of .bash_profile
