Enums with trailing white space cause error.

[jackstine]

If the enum is "aborted " this will cause an error. "aborted" is the accepted value. Would like to enhance so that trailing white spaces are allowed, if possible.

When calling the schema, err := graphql.NewSchema(schemaConfig) enums that have a trailing white space cause error.

Names must match /^[_a-zA-Z][_a-zA-Z0-9]*$/ but "aborted " does not.
