Require Poetry 1.2.0 (fixes CI errors)

Started to get errors in CI during the installation of dependencies,
apparently due to incompatibilities between Poetry and urllib3 >=2.0.
No idea why urllib3 >=2.0 only started to get installed now, perhaps
something changed in GHA's side.

Poetry 1.2.0 already requires urllib3 <2.0 thus solving the problem.

See python-poetry/poetry#7936
