Description

### Description & Motivation

The MLflow logger does not currently log the config.yaml file when using LightningCLI, meaning MLflow does not contain a complete record of an experiment

### Pitch

The config.yaml file to be logged as an artifact

### Alternatives

None, currently use a confluence page to link the MLflow run and config.yaml which is tedious

### Additional context

_No response_

Research direction

Start by locating the MLflow logger and the LightningCLI configuration handling in the repository. Confirm how config.yaml is produced and where logger artifacts are registered; the work is done when the configuration file appears as an artifact in the corresponding MLflow run.
