Updating the cardano-signer version

• Update the commit rev and sha256 found in the srcRepo fetchFromGitHub function and save

• Reload the devShell to preload the new source repo

• Run update-yarn-file to generate a new yarn-$SHORT_REV_OR_REL_TAG.lock

• Git add the new lock file

• Make sure the build succeeds with:

  nix build -L .#cardano-signer

• Remove the old yarn-$OLD_SHORT_REV_OR_REL_TAG.lock file

• Git add the deleted old lock file

• Commit the changes, push and verify GHA CI passes

• Celebrate! :)
