[CI] Test coverage information is not completely carried over to codecov

[nibix]

On the PR #4380 I am noticing that the test coverage information that is displayed by codecov does not match the test coverage I see in my local dev environment. On first sight, it seems that the coverage from the integrationTest directory is missing.

For example:

Coverage reported by codecov for the class ActionPrivileges:

Coverage reported by Intellij just after running ActionPriviliegesTest (in integrationTest) :

While IntelliJ shows full coverage, codecov shows completely missing coverage.

My current suspicion is that the coverage information from integrationTest is not evaluated by codecov. But that's speculation for now, I could not find any clues so far where the issue might come from.

I just noticed that the ci.yml script uses actions/upload-artifact@v4 to upload the reports from test while it uses alehechka/upload-tartifact@v2 to upload the reports from integrationTest 🤔

[nibix]

Output of the Display structure of downloaded files step of the report-coverage job. The integration test data should have the name pattern integration-${{ matrix.platform }}-JDK${{ matrix.jdk }}-reports. This is missing.

I am now trying to see what happens if I use artifact instead of tartifact: #4802

[nibix]

The tartifact action was introduced in #3537. However, the explicit untar which was also introduced there is now missing from the ci.yml.
