Subject: [PATCH] ci(runner): Run tests on specific Ubuntu versions

Factors out runner OS into separate workflows that each call a shared
test matrix workflow. This allows CI status badges for each runner OS,
rather than a single status badge for all OSes.

Having a CI status badge for each supported runner OS allows
at-a-glance judgement of this Action's maintenance status.

Resolves: #106
