Allow custom error messages on input step regex validation

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

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

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

Hey @Jesse

Thanks for the message.

Can you send a build link to support@buildkite.com so we can take a closer look

Cheers!

Sure! I will send one now
