don't conflate builds with datasets

[eharkins]

This changes a bunch of places where I had used the word "build" when I really meant "dataset". For a clear explanation of the difference, see:
#271 (comment)

I think of a "build" as a workflow. seasonal-flu is a build. ncov is a build. I think of the products produced by these builds (eg ncov_global.json) as "datasets". One build may produce multiple datasets. Perhaps this makes the most sense when encountering Auspice JSONs like ncov_global_2020-06-01 where it's clear this a "dataset" distinct from the ongoing day-to-day rebuilds.

Sorry I didn't see that comment until just now Trevor but it really clarified the difference for me! In basically none of the cases where I had used "build" on nextstrain.org pages did I mean

a workflow

and instead meant

the products produced by these builds (eg ncov_global.json)

Thanks Eli! A couple thoughts:

This section is an index of public Nextstrain datasets for flu, organized by type. If you know of a dataset not listed here, please let us know!

Do we intend to allow non-core flu datasets to be included in this list? If this page is meant to replace /flu I'd keep it to just the datasets that live below /flu in the URL hierarchy. Otherwise, if we're keeping /influenza we could imagine separating this, like we do for /ncov vs /sars-cov-2.

Jump to our latest global SARS-CoV-2 dataset which is updated daily

I'd use slightly different language, perhaps: "Jump to the latest update to our SARS-CoV-2 globally-subsampled dataset which is updated daily"

We also maintain regional builds for Africa...

"We also keep updated regional datasets for Africa..."

Thanks @trvrb! I was under the impression that

this page is meant to replace /flu

so I removed language that suggests it's listing anything other than

just the datasets that live below /flu in the URL hierarchy

Let me know if you were intending the other way around.

For /sars-cov-2, I went with

Jump to our globally-subsampled SARS-CoV-2 dataset which is updated daily. We also keep updated regional datasets for...

I don't think we need to say "latest" if we are saying it's updated daily.

These changes are great. Thanks Eli. Looks like this may need to be rebased, but otherwise I think it's good to go.
