creates an augmented version of
static-site/content/allSARS-CoV-2Builds.yaml
by fetching the actual datasets
to get information about them such
as date updated and number of
tips to be displayed on the build
listing and map.

building on:
081bd55633133e586a3dae86617564e1f2854418
, which fetched community datasets listed
in static-site/content/allSARS-CoV-2Builds.yaml
in order to augment that list with metadata.
This takes the fetched community datasets
and includes them in the sarscov2 search
results database file. Still to-do is testing
this on the front end.

scripts/collect-search-results.js reads in a
list of builds in a manually maintained pathogen
build catalogue yaml file such as
static-site/content/allSARS-CoV-2Builds.yaml
and produces an augmented version with metadata
from each corresponding dataset.
(see 82e072d).
That augmented yaml file is stored on s3 and
fetched here to populate e.g the build-map
(front-end manisfestation of that pathogen build
catalogue on the page) with metadata about each
dataset (e.g. date updated).

this makes this component more
generally applicable for when we
want to have similar build catalogues
for other pathogens

we have a couple of scripts that are
utilities for creating and checking the
format of data resources behind pages
like nextstrain.org/sars-cov-2. This
generalizes the code in those scripts
so that they make sense when we
apply them to other pathogens in
the future

also update the github action using
scripts/collect-pathogen-resources.js

also note that upon merging this we
will need to update a link in the following
doc:
https://docs.nextstrain.org/en/latest/guides/share/sars-cov-2.html ;
the link points to:
scripts/check-sars-cov-2-builds-yaml.js
which is now called:
scripts/check-build-catalogue-yaml.js

this takes the augmenting of the build
catalogue and abstracts it into a function

fixes bug when running for seasonal-flu
introduced by work on this script. Better
logic overall for writing outputs and
printing messages

this directory contains components
which are now generally applicable
to any page that wants to display a
collection of info about any grouping
of builds (e.g. flu, groups, commeunity),
not just for sars-cov-2.
