Fix pipx install action

Fix pipx-install-action Windows compatibility issue

Replace BrandonLWhite/pipx-install-action@v1.0.3 with threeal/pipx-install-action@v1.0.0 in CI workflow due to Windows compatibility issues.

Changes:

• Switch to alternative pipx-install-action that works on Windows
• Add explicit package specification for poethepoet and poetry
• Resolves GitHub issue: Error: Cannot read properties of undefined (reading 'metadata') on Windows runner BrandonLWhite/pipx-install-action#62

Edit: received a reply from pipx-install-action maintainer with a fix: simply remove the breaking cache from GitHub Actions: this worked fine.

Thus I reverted the commit which introduced another action on Windows. The only change that this PR makes is pipx-install-action version upgrade.

Looks good to me as a quick fix to CI 👍 Copilot's suggestions around consistency probably make sense?

However, I am wondering about the reliability of the new action compared to the previous one: The code looks fine superficially. It's also a one-man-show, where the author seems to have limited time to maintain it, and I'm not sure it's in widespread use.

Maybe this would in fact be a reason to push for uv: It does come with a reusable action by the authors (see https://docs.astral.sh/uv/guides/integration/github/) which supports caching, and it can manage python and tools. (I think we could also use uv only in this role for now, and continue building with poetry.)

I started looking into uv and meanwhile received a comment under the issue with a fix, so received a reply from pipx-install-action maintainer with a fix: simply remove the breaking cache from GitHub Actions which worked fine.

Thus I reverted the commit which introduced another action on Windows. The only change that this PR makes is pipx-install-action version upgrade.
