Need way to easily access unit test code coverage data

[nusbaume]

A Github Action workflow in this repo generates a code coverage artifact (e.g. an HTML file) that contains statistics on the current level of unit test code coverage across the various files and modules in this repo. However, it is currently somewhat difficult to access this data, as one has to click through several Github tabs/pages, download the folder, and then unzip it.

Instead, it would be nice to have a way to put this HTML file (or the underlying code coverage stats) onto a website or dashboard somewhere so that it is easy to access, especially if it could be combined with other relevant repo stats (e.g. ESCOMP/CAM-SIMA) as well.
