[8.17] (backport #8084) ci(test): skip skipped tests from the Test JUnit output

[mergify]

What does this PR do?

Bump the gotestsum version and eemove skipped tests from the aggregated report.

Why is it important?

The integration tests reporting have a few non-critical reporting issues:

• Each test step has its own XML and HTML report in atrifacts (Build example)
• The reports contain many of skipped tests (example)

That affects:

• General test report readability
• Buildkite Test Suites show wrong AVG duration and failure percentage
