pin crds

[braingram]

The recent release of crds is incompatible with jwst crds run in non-serverless mode (which we use in the CI). This adds an upper pin that we can remove when a compatible release is available.

I saw you asked Jonathan whether this was needed for JWST. I'm all for this, it's easy to change back.
