Az cli in script asks raw.githubusercontent.com behind private firewall

### Describe the bug

We have a script that utilizes az cli for doing a job in AKS. The AKS cluster itself are behond a firewall for outgoing requests and when we run simple commands like `az --version` or `az login ...` it seems like requests towards `raw.githubusercontent.com` are done. This means that we need to open the firewall for `raw.githubusercontent.com` which again means that we open the firewall to all the public content on github which can include malware. Is this by design?

Github search on `raw.githubusercontent.com` in azure-cli github repository:

https://github.com/search?q=repo%3AAzure%2Fazure-cli%20raw.githubusercontent.com&type=code

There is also references to private repositories in the URLs used that seem to be archived and not updated anymore, for example: https://github.com/danielsollondon/azvmimagebuilder

### Related command

```
az -h
az login
az account set --subscription xxxxxxxxxxxxx
az aks get-credentials --resource-group xxxxxxxxxx --name xxxxxxxx --overwrite-existing
```

### Errors

No particular errors in place other than request we don't use that might fail in the background.

### Issue script & Debug output

No direct error

### Expected behavior

We expect the cli to have the information need in the Cli itself?
