CLI-3562: Error: update client failure: error updating CLI binary

I'm seeing the following error when trying to update confluent locally on Apple M1 using macOS 13.3.1 (a) (Ventura):

Suggestions:
Please submit a support ticket.
In the meantime, see link for other ways to download the latest CLI version:

```

However, I'm not seeing the issue Intel macOS 11.7.6 (Big Sur):

```zsh
➜ confluent update
Checking for updates...
New version of confluent is available
Current Version: v3.11.0
Latest Version: v3.12.0

```

In short, one needs do `sudo confluent update` instead `confluent update`. Thus, I believe that the `confluent` binary executable should invoke `sudo` in such situations.
