clarify if keying of top level site should be eTLD+1 based #2

Based on reading https://github.com/kyraseevers/Partitioning-visited-links-history/blob/e084b3ebfc6c5183decba8aaf71c9331e11d9b6e/README.md?plain=1#L48-L56 it seems a bit unclear what a "site" means in this context. Based on the infographic, it seems to be based on the eTLD+1, but even using just keying by top level origin could potentially work here.

Thanks for your question! Site here will be implemented as "schemeful site", which is eTLD+1 and scheme.

We did have some discussion of just keying by top-level origin. However, by keying by both frame origin and top-level site, it allows us to prevent sites embedded in iframes from determining the history of their embedders.
