Missing/inconsistent item groups on wooden blocks; wrong item group on white wool

(a) In creative inventory, there are two item groups (Building Blocks and Redstone Blocks) on oak variant redstone blocks: oak_fence_gate, oak_door, oak_trapdoor, oak_pressure_plate and oak_button.

But the same kind of blocks on the non-oak variants, only have one group (Building Blocks).

Non-oak variant including: spruce, birch, jungle, acacia, dark_oak, mangrove, bamboo, crimson and warped.

(b) There are two item groups (Redstone Blocks and Tools & Utilities) on oak_chest_boat and bamboo_chest_raft, but only one group (Tools & Utilities) on other variants.

Besides, their ordering in search tab is wrong. (due to missing first group)

(c)  There are two item groups (Colored Blocks and Redstone Blocks) on white_wool, there should be only one: Colored Blocks.
