Transitive vulnerability gives a warning in ktor-server-test-host-jvm

Hi,
In `ktor-server-test-host-jvm:3.1.0` Intellij raises a warning owing to a transitive vulnerability in Apache commons-codec before `1.13-RC1`.
Given that this is being used for testing, it's probably nothing more than a minor nuisance. Thought I'd raise it here just in case.


Start by inspecting the dependency declarations for the ktor-server-test-host-jvm module and determine which transitive dependency resolves Apache commons-codec below 1.13-RC1. Verify the resolved dependency and IntelliJ warning after the change; done means the vulnerable version is no longer selected without breaking the test-host module.
