v69b

This reverts commit 67bcaea71e. The sub-shell was required to prevent the updated umask from affecting later steps. It broke the permissions of the fetched assets for the control panel: https://discourse.mailinabox.email/t/admin-panel-broken-after-restore-upgrade/12112/24

Instead, the `$()` is replaced with just `()` to create a subshell without executing its output.
