Release notes 20.03->20.09 instructions may need an update (ACME)

[Ma27]

FYI the following issues may be related: ACME fails with JWS verification error · Issue #101445 · NixOS/nixpkgs · GitHub, https://github.com/NixOS/nixpkgs/issuesF/101981

That said, I fully agree that the release notes should cover the ACME changes
