The bulk update request #10993 has been approved by @nonamethanks.
create alias hair_tassel -> tassel_hair_ornament
create implication tassel_hair_ornament -> hair_ornament
Same thing, different name that makes tag easier to find. Tag is severely undertagged (ex. ningguang_(genshin_impact) -hair_tassel -alternate_costume). Most hair ornament tags also follow this format.
Edit: updated BUR to include implication to hair ornament together with NNT's implication BUR
