[DataPack] npcdata B grade arrows in 40 level mob drops (must be C grade)

[smeli]

только я непомню у кого оно было даже в ц1 мануальчике по дропу ето написано :)

krator, tamlin_orc_archer, dire_wyrm taik_orc_archer, vanor_silenos_grunt, stakato_queen_zyrnna are 41-46 lvls, but drop B-grade silver_arrow.

To be checked how is it in C4 and fixed. Most probably C grade arrows should be dropped here
