Improve default visibility of tremor info logs from packages

[anupdhml]

Description

Ensure info logs under the tremor namespace appear by default when tremor is run from our packages. This improves the debuggability for those tremor runs.

This behavior is aligned with the docker image's logger configuration: https://github.com/tremor-rs/tremor-runtime/blob/main/docker/logger.yaml

Performance

May lead to more logs being written to file by default but the effects on performance should be negligible.
