Netherite Sickle

[x] Get targets https://github.com/euphori/Dummy-Project-RGL/blob/fbee7b6e6c608210fbeb102c8ebda65200fa9d3b/data/scripts/netherite_sickle.ts#L112-L116 Consider a different approach for getting entities since this one mean another player will be immune to the ability.
[x] system.runTimeout https://github.com/euphori/Dummy-Project-RGL/blob/fbee7b6e6c608210fbeb102c8ebda65200fa9d3b/data/scripts/netherite_sickle.ts#L125-L151 Be careful when using system.runTimeout since the entity could be invalid in the future. Consider adding entity.isValid() for every timeouts.
```
mc.system.runTimeout(() => {
entities.forEach((entity) => {
    if(!entity.isValid()) return;
})
});
```
[x] Apply damage source https://github.com/euphori/Dummy-Project-RGL/blob/fbee7b6e6c608210fbeb102c8ebda65200fa9d3b/data/scripts/netherite_sickle.ts#L118-L124 Consider adding damager. Without damager, neutral mobs will stay passive (e.g spider during daytime)
```
entity.runCommandAsync(`damage @s ${amount} entity_attack @p`);
```
Or using the native API
```
entity.applyDamage(amount, {
cause: mc.EntityDamageCause.entityAttack,
damagingEntity: player,
});
```
