Add confirm option to allow automated updates on nk3 devices

[anotherbridge]

This PR introduces an option to the nk3 update subcommand that allows the update to be automated.

Changes

• Add option --confirm to confirm udpate.

Important

The automation is only allowed for updates of the firmware. Downgrades or other potential issues that require user interaction are NOT included in this option. I.e. the confirmation applies only to the functions confirm_download and confirm_update.

Note

I noticed that the update function for the Nitrokey FIDO2 uses -y or --yes for a similar flag. However, to stay within the naming convention of the class functions of the nk3 interface, I decided to name the flag --confirm.
