happa release v1.72.9

Security

• The container image no longer ships webpack source maps. They were uploaded to Sentry during the build and then baked into the nginx image as well, where they were publicly downloadable and made up roughly four times the weight of the bundles they described. Sentry symbolication is unaffected. Reported via bug bounty; internal tracking issue giantswarm/giantswarm#37469 (#4879).
