Improve Functional Tests related to credential core commands

Context

It is possible to perform functional test (cf our Developer Guide) using Github Actions, to test the behaviour of Ritchie CLI core commands.

To do so, the team created an action: test-cli-commands-action

At the beginning, this action only allowed to test command lines with SUCCESS returns. But now, it also allows to test command lines with ERROR returns.

As SUCCESS scenarios are already tested for credential commands, an improvement would be to add ERROR scenarios following the same logic.

Why is this needed

• To improve the tool quality and the development experience.
