feat: add OUTPUT_DIR environment variable support to crd-extractor.sh

Allow specifying a custom output directory for generated CRD schemas
by setting the OUTPUT_DIR environment variable. This enables users to
generate schemas in their current directory or any specified location
instead of the default ~/.datree/crdSchemas.

Also updated the success message to show the actual output directory
used and adjusted the example commands to use the correct path.
