`HelidonTest` docs do not describe interaction with MicroProfile Config profiles

[barchetta]

Environment Details

• Helidon Version: 4.0.9
• Helidon MP

Problem Description

The HelidonTest Documentation:

• https://helidon.io/docs/4.0.9/mp/testing
• https://helidon.io/docs/4.0.9/mp/testing-ng

Does not describe the interaction of HelidonTest with MicroProfile Config Profiles.

Specifically:

1. By default a MicroProfile Config profile named "test" is defined.
2. You can't change the profile with the mp.config.profile system property (which is the normal way)
3. You can change the profile using @Configuration
