Subject: [PATCH] ci: Remove code coverage job (#429)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# What ❔

Removes code coverage CI job & related stuff.

## Why ❔

We don't really use it. For now, it's just bloat.
Additionally, it's likely to be misconfigured/suboptimal. For the next
attempt to have (and actually use) code coverage, it'll be better to
start from scratch and do proper research.
