[p-glaum]

Closes # (if applicable).

Changes proposed in this Pull Request

Checklist

• [ ] add try except similar to make_summary to allow plotting of comparison even though not all runs are present yet

• [ ] think about making a dictionary in config.yaml of what to plot, i.e. "total_cost" for carrier="all" and "energy_balance" for all individual carriers

• [x] I tested my contribution locally and it seems to work fine.

• [x] Code and workflow changes are sufficiently documented.

• [x] Changed dependencies are added to envs/environment.yaml.

• [ ] Changes in configuration options are added in all of config.default.yaml.

• [ ] Changes in configuration options are also documented in doc/configtables/*.csv.

• [x] A release note doc/release_notes.rst is added.
