Subject: update Let's Encrypt trust chain

Drop 'DST Root CA X3', use 'ISRG Root X1' instead. The migration code
makes sure that...

 * the intermediate certificate 'R3' is signed by 'ISRG Root X1'
 * 'ISRG Root X1' is self-signed, not cross-signed by 'DST Root CA X3'
 * 'DST Root CA X3' is finally gone
