Truncate CRD Description Fields to 50 Characters

[ayushsatyam146]

Changes

Adding a TruncateField transformer and using it to truncate CRD description fields from the kodata/release.yaml manifest. The CRDs for Shipwright Build objects are very large, resulting in a validation error from Kubernetes when we try to create the CRDs with Manifestival.

Partially addresses #184
