Commit linter changes automatically when merging PRs

**Is your feature request related to a problem? Please describe.**
Currently, it's up to the developers to remember to commit the changes that `black` and `isort` propose.

**Describe the solution you'd like**
We can add a task in the github actions workflow that can commit the changes `black` and `isort` propose when merging a PR into `dev` or `main`.

**Describe alternatives you've considered**
Have developers install a precommit hook.
