pywrangler - support for package managers other than npm?

As far as I understand, pywrangler implements a few things specific to python and proxies the rest to the node `wrangler` tool.

However, I noticed this is done with npm/npx. Would it be worth checking for the presence of a lock file to detect what package manager the project is using, to support other package managers such as pnpm?

If you think this is worth implementing, I'd be happy to submit a PR.
