Ensure the value is returned as a date

[solocommand]

When passing a literal value for a date (rather than a defined variable definition), the value is not properly transformed into a Date.

Assuming the following pseudo setup:

scalar Date
query {
  isDate(date: Date!): String
}

const { DateType } = require('@limit0/graphql-custom-types');
const resolvers = {
  Date: DateType,
  test: (_, { date }) => typeof date,
};

Currently works:

query IsDate($date: Date!) {
  isDate(date: $date)
}

{ date: 1664427600000 }

Should work but does not

query {
  isDate(date: 1664427600000)
}
