title: Yup with Formik, LessThan or Equal
body: <p>I'm using something like this:</p>
  
  <pre><code>schema.number
          .lessThan(
            value,
            `You own only ${value}.`)
  </code></pre>
  
  <p>It works great. If, however, if value = 60, all numbers up to 60 work, but without 60. I can't do: value + 1. Is there any method like: lessThanOrEqualto()?
  I need (∞; 60>
  I have (∞; 60)</p>
