fix: issues with mindthegap deplotment (#660)

**What problem does this PR solve?**:

This adds trust-manager to allow us to use self hosted helm charts in
mindthegap. See:
kubernetes-sigs/cluster-api-addon-provider-helm#104

We can think about this in a couple of different parts:

1. Installing trust-manager and CRDs. We need to install trust manager
so that we can create a certificate bundle with our self signed cert to
caaph-controller-manager. We pull the CRDs separately because we are
unable to use them in our templates because they aren't available at
that time. See the comment in the script for more details.

2. Modifying CAAPH to use the bundle. This is done through a job it has
a corresponding Service Account/Role/Role Binding.

3. Various little fixes. ie changing repository url and versions to
using `v`

I tested this by creating a docker cluster.

The helm chart proxies use this value

```yaml
