traefik2-loadbalancer: Upgrade to v2.11.1; resolves #734

[kallisti5]

• Correct spelling mistakes in post-install readme
• Add missing CRD definitions
• Sync roles to traefik 2.11 examples while keeping custom civo naming

Thank you for wanting to submit a Pull Request to the Civo Kubernetes Marketplace repository!

Tested functional on civo. Traefik is the default ingress controller when applied. v2.11.1 is just coming out, but doesn't have an official image yet so went with v2.11.0.

There's a few missing CRD definitions, but substantially better than what is offered now.

@aakashnagpal4567 can you test this PR for Kubernetes 1.27 talos, 1.28 k3s and 1.29 k3s?

@aakashnagpal4567 can you test this PR for Kubernetes 1.27 talos, 1.28 k3s and 1.29 k3s? will test this

[aakashnagpal4567]

@saiyam1814 I have tested this, and it's working fine for 1.27 Talos, 1.28 k3s and 1.29 k3s

I can look into upgrading traefik2-nodeport with similar changes next. I mostly upgraded these because it makes using civo a lot easier :sweat_smile:.

I'd recommend bumping to 2.11.1 when it comes out, but that should be a pretty minor change since these cluster roles, CRD's etc should work for 2.11.x

Thanks for the PR!
