Add a security.txt
A security.txt file is a standardized file that contain key contact informations to help security researchers contact a website owner to patch a vulnerability.
See https://securitytxt.org/ to generate a file.
It needs to be located at /.well-known/security.txt
or at /security.txt
Maybe we can add one for www.laquadrature.net and technopolice.fr
