Convert <markdown> component to JS and add basic tests

As an initial step towards cleaning up the annotation
editor component, convert it to JS and add basic tests.

The conversion was automated using
[decaffeinate](https://github.com/decaffeinate/decaffeinate)
with a small amount of subsequent cleanup.

The tests are very basic at the moment and cover
just the read-only/editing states and rendering
of markdown and LaTeX
