[Issue] azd pipeline config - auth type ignored

[jasontaylordev]

Output from azd version
azd version 1.4.2 (commit 694107e)

Describe the bug
When I run the commands:

azd env new EnvName
azd pipeline config --provider github --auth-type federated  --principal-name sp-EnvName

The resulting service principal is created with both client and federated credentials.

To Reproduce
To reproduce the behavior, run the commands:

azd env new EnvName
azd pipeline config --provider github --auth-type federated  --principal-name sp-EnvName

Then navigate to Azure Portal > Microsoft Entra ID > App registrations > All applications > sp-EnvName > Certificates & secrets.

Note that both the Client secrets and Federated credentials have values.

Expected behavior
When specifying --auth-type federated, I expect that client credentials will not be created in Entra ID or configured in GitHub.
