PHP_FPM_ENV_VARS never validates

[gease]

Based on the comment #111 (comment) I tried to add PHP_FPM_ENV_VARS to environments variables. But it always fails: if it is added as array the container does not start with the message
validating ...: services.php.environment.PHP_FPM_ENV_VARS must be a boolean, null, number or string
When it is a string, the container exits immediately with message in the logs
panic: template: titleTest:25:43: executing "titleTest" at <jsonArray (getenv "PHP_FPM_ENV_VARS")>: error calling jsonArray: invalid character 'E' looking for beginning of value
Obviously, environment variables in docker compose cannot be arrays:
docker/compose#4249

you need to pass json array as a string PHP_FPM_ENV_VARS: '["DB_USER","DB_NAME"]' in compose file or pass in via .env as PHP_FPM_ENV_VARS=["DB_USER","DB_NAME"]

we updated our docs with this info, thanks
