bug: cortex update stdouts "Update cortex sucessfully" even when update failed

[freelerobot]

Cortex version

v65->v67

Describe the Bug

1. User runs cortex update
2. For some reason update fails (cut wifi halfway), we still log "Update cortex successfully"
3. Expected: stdout that the update failed, missing permissions, etc.

❯ cortex-nightly -v
v0.5.0-65

A new release of cortex is available: v0.5.0-65 -> v0.5.0-67
To upgrade, run: cortex-nightly update
❯ cortex-nightly update

2. And everything worked fine

Add @vansangpfiev here to help modify the update message to the user. Change from cortex-nightly update to sudo cortex-nightly update since cortex-nightly is in /usr/local/bin, which requires root permission to replace.

The core issue is that updates can fail (for various reasons) but we still stdout to users that it was successful. We need better error handling here.
