Create line chart of UK confirmed corona virus cases

I was having trouble tracking the growth of corona virus cases in the UK.
Thankfully someone is publishing some daily COVID data as JSON. I downloaded
that data manually and plotted it using the chart.js library as a programming
exercise with Mimi.

Now I'm attempting to deploy to https://wpcarro.dev/covid-uk.

TODO(wpcarro): Prefer the live API data instead my soon-to-be-stale downloaded.
