Updating OpenAPI spec

Change the desired types, then run these commands, with the linked Enterprise repo:

go test --tags "pro" -timeout 30s -run ^TestIntegrationOpenAPIs$ github.com/grafana/grafana/pkg/extensions/apiserver/tests -count=1

./hack/update-codegen.sh scope

This should generate a diff in the Enterprise repo. Make sure to open a PR there too.
