New release: cardano-signer 1.20.1

## Release Notes / Change-Logs

* CIP100 Verification and Canonize
    - Bugfix: Corrected a bug where doublequotes that are already escaped in the body content to form the canonized body array were escaped again. This only affects the --json-extended output, but not the verification itself.
