Bushes are not replaceable

Despite acting like other types of grass, which indeed are replaceable, bushes are not considered replaceable. This also results in them being missing from the #minecraft:replaceable block tag, which prevents them from acting as enchantment power transmitters.

Firefly bushes are also not replaceable with similar effects; this issue is described separately in MC-279915.

Expected results

Bushes can be replaced by other blocks and be placed between bookshelves and enchanting tables without affecting the enchantment choices.

Actual results

Other blocks get placed on the side of bushes, and enchantment possibilities are affected by the placement of a rogue bush.
