Failed to load subscription client when CDN is enabled

[sr1977]

When I configure CDN to be enabled, with a subscription endpoint specified - I'm getting a 404 error with the loading of subscriptions-transport-ws-browser-client.js - it appears to be defaulting to being served locally, which I think is down to this:

graphql-spring-boot/graphiql-spring-boot-autoconfigure/src/main/java/graphql/kickstart/graphiql/boot/GraphiQLController.java

Lines 113 to 114 in fe6d8c0

	replacements.put("subscriptionsTransportWsBrowserClientUrl", joinStaticPath(staticBasePath,
	"subscriptions-transport-ws-browser-client.js"));

The app is hosted in k8s, so I don't want to have to put in complex ingress rules for this. I have another app without a subscription and that works fine.

I am using graphiql-spring-boot-starter:7.1.0 and my application.yaml has:

graphiql:
  mapping: /graphiql
  cdn:
    enabled: true
    version: 0.17.5
  endpoint:
    graphql: /graphql
    subscriptions: /subscriptions

I'm seeing the same issue with graphiql-spring-boot-starter:8.0.0 as well.

Upgraded default GraphiQL CDN version to 1.0.6 too and refactored the subscription-transport-ws dependency to load the last compatible version using CDN too.
