docs: // Parse is a function to parse line by line any io.Reader supplied and returns the valid Env key/value pair of valid variables.
  // It expands the value of a variable from environment variable, but does not set the value to the environment itself.
  // This function is skipping any invalid lines and only processing the valid one.
