870cd337 - fix: testing in Windows and add missing dev dependency (#2340)

fix: testing in Windows and add missing dev dependency (#2340) This changes addresses two issues. First, we add `setuptools` to the dev dependencies in order to debug tests locally with an IDE, especially with PyCharm. All dependencies dev dependencies should be installed with `poetry install --extras "dev"`. Second, we use PurePosixPath instead of Path for URL paths to fix issues with testing in Windows. This ensures that forward slashes are used as the path separator regardless of the operating system. Closes https://github.com/hwchase17/langchain/issues/2334
