Poetry 2.0 migration

Poetry has released a new version that includes several improvements and optimizations. Our current project is compatible with the latest version, but some deprecated fields are not backward-compatible.

The major change is the introduction of compatibility with the `project` section in pyproject.toml, as defined in [PEP 621](https://peps.python.org/pep-0621/).

We are also using [Poeblix](https://github.com/spoorn/poeblix) to build the project, but it is no longer being updated. We may need to find a replacement or discontinue its use when we migrate to Poetry 2.0.

For more details, refer to the official announcement: [Poetry 2.0.0 Release Blog](https://python-poetry.org/blog/announcing-poetry-2.0.0/).
