fix: remove sudo from dependency installer invocation

The installer binary handles sudo internally for dependencies that require
it (OpenTofu, Ansible, LXD). Running the entire binary with sudo causes
cargo-machete installation to fail because cargo is not in sudo's PATH.

cargo-machete is installed via 'cargo install' and doesn't need sudo.
