🐞 Bug report

Describe the bug

The 3.1.0 release of the helm chart for the zap-advanced scanner does not include the default session and authentication scripts despite the work done in #597.
It seems the regression was introduced by the changes to scanners/zap-advanced/.helmignore in #622

Steps To Reproduce

Pull latest (3.1.0) release of the zap-advanced helm chart.

Expected behavior

The recently pulled chart should include the scanner default scripts.
