CI: update notary test certificates

[thaJeztah]

fixes #2412

opening as draft, as I want to add a script to do this

[thaJeztah]

I'll do the script in a follow up; I generated these certificates with a slightly modified version of https://github.com/dmcgowan/quicktls with this patch applied: dmcgowan/quicktls#3;

GO111MODULE=off go get -u github.com/dmcgowan/quicktls
cd e2e/testdata/notary || exit 1
quicktls -org=Docker -with-san notary-server notaryserver evil-notary-server evilnotaryserver localhost 127.0.0.1
cat ca.pem >> notary-server.cert
mv ca.pem root-ca.cert
cp notary-server.cert notary-server.key root-ca.cert ../notary-evil/
