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
