Add pywhatwgurl to the list of Python implementations

I'd like to propose adding pywhatwgurl to the list of WHATWG URL Standard implementations. It is a pure Python implementation designed to be a small, spec-faithful library for parsing, serializing, and manipulating URLs.

We recently made the repository public and published it to PyPI. Our primary goal is to provide the Python ecosystem with a robust, highly compliant parser that stays closely aligned with upstream changes to the standard.

Here are a few highlights of the project:

• High Conformance: Achieves 100% compliance with the core URL parsing tests based on the official Web Platform Tests (WPT). (Note: IDNA/ToASCII has known limitations due to underlying Python libraries being strictly RFC 5891/5892 rather than UTS46, but core parsing is fully compliant).
• Familiar API: Provides full, browser-like URL and URLSearchParams APIs.
• Commitment to Freshness: We have automated CI workflows running on a weekly schedule that fetch the latest WPT URL test data, run the test suite, and open automated PRs ensuring the parser stays securely synced with the living standard.

Thanks for your incredible work on the standard! Please let me know if you need any adjustments to the PR or additional information.

Looks good modulo an awkward nit.

I hate to ask this, but could you please undo this change? We use this list for people that contributed directly to the standard itself, not the wider ecosystem.

No problem at all, I've just reverted that in 2912fbe

I only added it initially because the README.md mentioned: "Please add your name to the Acknowledgments section in your first pull request, even for trivial fixes" — but that totally makes sense it's intended for standard contributors. Thanks for clarifying!
