chore: Remove the tedious message about loguru

[frascuchon]

When loguru is not found in the system, a message is shown again and again. This PR just removes the message.

For future versions, we can include better logging customization that can be explicitly enabled.

See #1305

Could we create an issue and label it as a good first issue?
