feat: add script to populate local.properties from environment variables

This commit introduces a shell script `before-ci.sh`.

The script reads keys from `local.properties.example` and for each key, it retrieves the corresponding value from the environment variables. If a value is found, the key-value pair is appended to the `local.properties` file.

This allows for dynamic configuration of build properties based on the CI environment.
