[bugfix] Update metaGEM.sh

Fix path to `config.yaml` file for `metaGEM.sh` script.
As mentioned in #150, the `metaGEM.sh` wrapper cannot find the config file in question, a bug that was introduced after restructuring the repo to be compliant with the snakemake workflow catalogue [rules](https://snakemake.github.io/snakemake-workflow-catalog/?rules=true).
