Describe the bug

After the app is successfully deployed and running, the web interface is still unavailable due to a misconfiguration in traefik. The traefik dashboard reports the following error for the Splunk router.

middleware "default-chain-basic@kubernetescrd" does not exist 

I can see that the middleware mentioned above is indeed set in the ingress annotations:

root@truenas[~]# k3s kubectl describe ingress splunk -n ix-splunk                 
Name:             splunk
Labels:           app.kubernetes.io/instance=splunk

                              meta.helm.sh/release-namespace: ix-splunk
                              traefik.ingress.kubernetes.io/router.entrypoints: websecure
                              traefik.ingress.kubernetes.io/router.middlewares: default-chain-basic@kubernetescrd
Events:                       <none>

However, I can see that a middleware with the name: ix-traefik-chain-basic does exist in traefik.

I suspect this is caused by the outdated version of the library-charts for the Splunk Chart. The version used is 11.1.2 and I can see that default is indeed is being the default middleware prefix for the library charts versioned 11.1.2:
https://github.com/truecharts/library-charts/blob/0898c5dee7b0ff9bb11ab2b4c8c2870cce61a697/charts/common/templates/class/_ingress.tpl#L37

If simply bumping the library version is enough, I am happy to raise a PR.

To Reproduce

1. Install latest version of Splunk app from incubating train
2. Configure ingress with values mentioned in Application Configuration
3. Inspect traefik dashboard

Expected Behavior

Splunk service is reachable via traefik and the specified hostname.

I've read and agree with the following

• I've checked all open and closed issues and my issue is not there.

Incubator means "alpha" "beta" or "unstable", it might not work at all or be heavily outdated.
Hence we don't take bugreports for them either,
