chore: Set patch coverage to informational (always pass status check)

[bryphe-coder]

Came up in our 1:1 discussion - we have cases where the patch diff might not hit the coverage goal, but it doesn't overall coverage. An example would be changing a single line in a /pages component to fix a typo - that would have 0% coverage, but not impact overall coverage.

This just sets the patch check to informational, so the status check always passes (it still reports the diff %, though, which is useful for cases in general): https://docs.codecov.com/docs/commit-status#patch-status
