Improved poetry configuration for keiko and octopoes

[Darwinkel]

Changes

Improves the pipeline for managing dependencies through poetry. I constrained this PR to refactoring keiko and octopoes, since those modules already use poetry. After this PR, we can roll it out to the other modules.

Also, I removed some of the tooling config from the octopoes/keiko pyproject.toml's as those configs are centrally managed by pre-commit through the root's pyproject.toml, and upgraded some workflows to Python 3.11.

Issue link

Relates to #735 (third attempt :-))

Proof

See CI.

Some notes with regards to the feedback from the previous PR's:

• Dynamic versioning (Replace poetry with pip-compile for keiko and octopoes #1038 (comment)) appears to be non-trivial: https://pypi.org/project/poetry-dynamic-versioning/
• The yml linter complains when applying path filtering in the style of **/requirements*.txt

Ah, interesting. The CI automatically updates point releases. We should probably pin point releases in pyproject.toml to prevent that. Probably also better for dependabot.

Fixed!

I'd say this PR shouldn't close #735 because it only changes Keiko and Octopoes, not the other services. We'll want to change those as part of #735 too.

edit: changed the first post to "Relates to" instead of "Closed"
