Build process fails due to references to defunct kubernetesjsonschema.dev

[ciaranjohnston]

Expected behavior

Container images are successfully built and builds succeed.

Actual behavior

Builds are failing: https://github.com/kptdev/kpt/actions/runs/22597384156/job/65525954615#step:5:645 due to bad SSL certificate on https://kubernetesjsonschema.dev/

        curl failed to verify the legitimacy of the server and therefore could not
        establish a secure connection to it. To learn more about this situation and
        how to fix it, please visit the web page mentioned above.

Information

Proposal is to update to this:

curl -sSL 'https://raw.githubusercontent.com/yannh/kubernetes-json-schema/master/master-standalone/configmap-v1.json' -o $SCHEMA_DIR/configmap-v1.json

Steps to reproduce the behavior

Run the command

$ curl -sSL 'https://kubernetesjsonschema.dev/master-standalone/configmap-v1.json'
