nerdctl login used against a basic auth server will error in confusing ways after hammering the server

[apostasie]

Description

Passing wrong credentials against a basic auth registry will result in nerdctl trying repeatedly (ten times).

Then spit out:
too many 401 (probably)

Followed by a failed to call rh.Client.Do: Get \"https://10.4.0.1:5000/v2/\": tls: failed to verify certificate: x509: certificate signed by unknown authority" i=1 which does not make sense here.

Steps to reproduce the issue

1. Start a registry with basic auth
2. Login using nerdctl

Describe the results you received and expected

Received:

• confusing error message
• repeated attempts with the same wrong credentials instead of bailing out

Should have received:

• more clear error message
• try once and stop
