Description

Fix #3473

While we had already addressed the vulnerability with #2180, this helps snyk not flag it. You can test it by setting up snyk locally and running snyk code test
Also removed extractall from tests and replaced with safe_extract.

@astrojuanlu It flags the same issue, actually, but brings down the severity from high to medium -

Great work! ⭐ I'd suggest adding it to the release notes as well to make it visible we take security seriously in Kedro.

It's a shame bandit still flags it.. hopefully they fix it soon.
