Replace Item unnecessary command linting suggestion does not cover all use cases

[ThomasOrs]

The avoid unnecessary command linting suggestion for /replaceitem does not take into account use cases which are not achievable in script apis such a setting equipment on non player entities.

/replaceitem allows creators to set equipment slots on any entity, ie /execute as @e[type=minecraft:zombie] run replaceitem entity @s slot.weapon.mainhand 0 iron_axe meanwhile non-player entities do not have the equipable component accessible.

Adding support to the script API is on the backlog, but in the interim we will look into cleaning up the linting rule.
