Hello,

We have a pipeline where we have added a relatively complex regex validation to an input following the instructions from [Input step | Buildkite Documentation](https://buildkite.com/docs/pipelines/input-step#input-validation)

The resulting error message when the regex fails is not very readable. For example:

 ![image](https://us1.discourse-cdn.com/flex016/uploads/buildkite1/original/2X/7/74ba4795c9acd0000cba216b8a150c5136bffa45.png)

Would it be possible to add a custom error message for when the validation fails?
