Print error message when talos.config endpoint return an error

[paucampana]

Feature Request

If a user uses talos.config talos parameter when building an ISO, it works fine when the endpoint returns the machineconfig. However, when the endpoint fails, the user only sees in the logs the error code XXX (for example: received 403). Is it possible to add some more info here? For example printing the error message returned by the talos.config endpoint.

Extra info

• Tested in Talos 1.5
