This issue is imported from pivotal - Originaly created at Oct 26, 2020 by Michiel Kodde

Jquery and Bootstrap resources are tracked in the webfolder of tiqr. This is potentially harmfull as the security scanners are not able to test these dependencies for known vulnerabilities. For example. The selected version of JQuery has 4 known vulnerabilities

https://snyk.io/test/npm/jquery/1.11.3

These packages should be tracked using yarn.

I dont think this dep is still used.

It needs to be removed from the stepup-bundle, then it will be gone here.
