Mojang renamed the following block tags for consistency in 26.1, VB currently only adds empty tags for them, this breaks client-side block place prediction.

Tests showed this caused the client not to play the arm swing animation and block place sound when placing bamboo and other blocks.

Diffed the block tag json in 26.1 and 1.21.11, can be safely renamed.
