ci: lower codecov severity to informational

[michaeladler]

Instead of failing the CI pipeline when code coverage slightly decreases, this change sets the codecov severity to informational. This allows the reviewer to assess the coverage changes and make the decision on whether to accept the changes, rather than automatically failing the build. This provides more flexibility and context for the coverage changes.
