[da1910]

📝 Description of the feature

Poetry projects created with this template work great, but poetry install does not play nicely with pre-commit run. Poetry removes packages that are not in the lock file, and pre-commit installs PyYAML amongst other things, this is then removed on subsequent invocations of poetry install will uninstall one or more dependencies of pre-commit

💡 Steps for implementing the feature

Add pre-commit as an entry in the [tool.poetry.group.dev.dependencies] group
