Description

Makes the loofah dependency requirement looser to unblock the ZBT team. I tested this with ZAT and confirmed unit tests all still pass.

See https://zendesk.slack.com/archives/C1230V1CG/p1704180155370169 for context.

Hello Team Vegemite 👋 In our framework (ZBT) we are using zendesk_apps_support, and we are unable to bump rack to address the vulnerability reported by Snyk because of unresolved dependencies. zendesk_apps_support requires loofah to be >= 2.3.1', '< 2.20.0, but in ZBT we must bump loofah to 2.22.0 in order to allow us to upgrade rack.
Would you be able to loosen the version restriction so that we can perform the gem upgrade for our framework? Than
