Security scan is still using X-XSS-Protection

I think X-XSS-Protection should no longer be used, but scan.nextcloud.com still makes use of it.

Thanks for reporting this

I’ve removed it from the code already, I just needs a deployment. I will update the github ticket once that’s done:

github.com/nextcloud/server
