#sand isn't used in the #enderman_holdable block tag

The Bug

Despite the #enderman_holdable tag having red sand and sand in it, it doesn't use the block tag #sand

Reproduce

• Download the nylum data pack below
• Put the pack onto a world
• Get a sponge
• Look at the tags on the sponge (you can also look at the packs code to see what tags sand is apart of)
  Notice it is only apart of #sand & #bamboo_plantable and not #enderman_holdable
