[go-server] add field name in parsing error messages (#18533)
Currently when a parsing rule of a field is not respected (eg: min/max
value, required, ...), the api only returns an  error message without
providing the field name to help the user to fix the request. This commit
add the field name to the error message to help the user of the API.
