The manual stated that yaml_parse_file() returns false on failure.
In practice, the function returns either the parsed value (usually an array) or a string containing an error message, and does not return false.
This PR updates the return value documentation to reflect the actual behavior observed with ext-yaml on PHP 8.2 and 8.3.
