fix(test): add is_ranged field to stale AttackRequest in pvp_combat_determinism

The RangedAttack dispatch work (e8dd4a85b) added `is_ranged` to
`AttackRequest`, but the mc-golden-tests pvp_combat_determinism test still
constructed the struct without it, breaking `cargo test --workspace` (and
the cloud fleet) with E0063. Set `false` for this melee-combat test,
matching the mc-turn PvP tests.
