fix(deps): check passwordless sudo before prompting with sudo -v (#4980)

sudo -v asks for a password with sudo-rs (Ubuntu 25.10+) even with
NOPASSWD, and with classic sudo when the user also matches the default
%sudo rule. Try sudo -n true first and only fall back to the sudo -v
prompt when passwordless sudo is not available.
