Export JAVA_HOME to xcodegen (#606)

* Explicitly pass environmental variables to Xcode build script.

* Integrate COMPOSE_DEMO_APPLE_TEAM_ID variable into xcodegen

* Update prebuild script in project.template.yml

Refactor the prebuild script for better readability and maintainability. Removed unnecessary environment variables and simplified Gradle command.

* Update gradle CLI script in project.template.yml

Refactor prebuildScripts in project.template.yml for better readability and maintainability. Separate relevant commands into distinct lines to improve code structure.

* Add echo JAVA_HOME in build script
