Upgrade to poetry 1.2 and separate the dev-dependencies into groups

[jond01]

Instead of installing all the dev-dependencies on each nox session: https://github.com/cjolowicz/hypermodern-python/blob/ed593b8399dd94e2fe6f618aca8ea5f43710b541/pyproject.toml#L21-L42 Split the dev-deps into groups - a feature provided by poetry 1.2: https://python-poetry.org/docs/managing-dependencies/#dependency-groups Install only the relevant dependencies.

This requires upgrading poetry to 1.2 (e.g., 1.2.2): https://github.com/cjolowicz/hypermodern-python/blob/ed593b8399dd94e2fe6f618aca8ea5f43710b541/.github/workflows/tests.yml#L17

Suggested groups:

• test
• lint
• typing
• docs
