Add a section on References

The explainer currently only mentions the HTML Design Principles. I think it's appropriate to also mention the Web Platform Design Principles.

Interesting, and agree these are an informative reference. Will read, and add references as appropriate / that I recognize as applying in particular. @shepazu recommended that I write two separate 'explainers', one which is a high-level one/two page executive summary-type explainer, and this one which goes deeper and in principle tries to follow the TAG advice on explainers, resulting in a lot of detail, which has resulted in people complaining that the explainer is too long.

Keeping this issue open as a way of saying to self: "Add a section on References", per the TAG guidelines template.

Found a good reference by browsing this document, the TAG Ethical Web Principles. The latter could even factor into the requirements and use cases, I dare say.

The TAG Ethical Web Principles are linked from the Web Platform Design Principles.

And when you submit an Early design review to TAG there's an item to check if you've reviewed the Web Platform Design Principles, nothing about HTML design principles, I believe the former is simply treated as a successor to the latter.

We should close this issue out by replacing HTML design principles with Web Platform Design Principles. Don't think there's anything else to be done here.
