Update rancher-version annotation in kubewarden-controller chart

[jordojordo]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current Behavior

The annotation for catalog.cattle.io/rancher-version is currently set to >= 2.6.0-0 <= 2.8.100-0 This is causing any v2.9-x versions to not show the latest controller chart.

Expected Behavior

This should be updated to include 2.9.100-0 as rancher-alpha charts contains a 2.9.0-alpha1 version:

```console $ helm search repo rancher-alpha/rancher -l --devel NAME CHART VERSION APP VERSION DESCRIPTION rancher-alpha/rancher 2.9.0-alpha1 v2.9.0-alpha1 Install Rancher Server to manage Kubernetes clu... rancher-alpha/rancher 2.8.4-alpha1 v2.8.4-alpha1 Install Rancher Server to manage Kubernetes clu... rancher-alpha/rancher 2.8.0-alpha2 v2.8.0-alpha2 Install Rancher Server to manage Kubernetes clu... rancher-alpha/rancher 2.8.0-alpha1 v2.8.0-alpha1 Install Rancher Server to manage Kubernetes clu... ... ```

Steps To Reproduce

1. Bring up an instance of Rancher 2.9.0-alpha1
2. Attempt to install the kubewarden-controller chart
3. See versions are limited to 1.1.1 and below

Environment

- OS: Linux
- Architecture: amd64

Anything else?
