Use Securedrop's Official https-everywhere ruleset
Let's create a fixup for #28005 (moved).
Official ruleset is now: https://securedrop.org/https-everywhere/
New signing key: https://github.com/freedomofpress/securedrop-https-everywhere-ruleset/blob/master/release-pubkey.jwk (also in footer of securedrop.org)
The repository for storing the official HTTPS Everywhere ruleset channel is here: https://github.com/freedomofpress/securedrop-https-everywhere-ruleset
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
