Add in the debugpy configuration which has somehow got lost along the
way. The debugpy port is already exposed in docker-compose.yaml and so
this config was always _meant_ to be in the development image but seems
never to have been added.

This unblocks support for debugging running images in IDEs such as VS
Code.

Closes #106

Add base scaffolding to allow auto-generated documentation. Take the
opportunity to bump the CI template versions.

When running in the context of renovatebot, copier does not have poetry
or git commands available so don't try running them.

As noted in [1], code coverage reports are not currently being uploaded
and so MR diffs are lacking coverage indicators. Port the fix from [2]
to write them into the expected location.

[2] uis/devops/iam/activate-account/api!30

The auto-update performed by renovatebot makes a line-ending which
pre-commit doesn't like.

Provide an initial renovatebot configuration which knows how to keep tox
and tox additional requirements up to date.
