Disable codecov comments (jazzband#1409)

* Disable codecov comments

Avoid spamming reviews with verbose comments
from codecov. The coverage check report is
available separately, one click away, just like any
other check jobs.

This will make it easier to perform reviews.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci
