Examples provided in this repo are not getting synced

I basically followed the examples in the repo here but my hello-provider-github is not getting in sync.

1. Installed provider
```
apiVersion: pkg.crossplane.io/v1
kind: Provider
metadata:
name: provider-github
spec:
package: xpkg.upbound.io/coopnorge/provider-github:v0.3.2
```
2. Added the credentials and connection to github
```
---
apiVersion: v1
kind: Secret
metadata:
name: provider-secret
namespace: crossplane-system
type: Opaque
stringData:
credentials: "{\"token\":\"${GH_TOKEN}\",\"owner\":\"${GH_OWNER}\"}"

---
apiVersion: github.upbound.io/v1beta1
kind: ProviderConfig
metadata:
name: default
spec:
credentials:
source: Secret
secretRef:
name: provider-secret
namespace: crossplane-system
key: credentials
```
3. Added the hello-provider-github repository
```
---
apiVersion: repo.github.upbound.io/v1alpha1
kind: Repository
metadata:
name: hello-provider-github
spec:
forProvider:
visibility: public
gitignoreTemplate: Terraform

kubectl -n crossplane-system get Repository hello-provider-github
