Bamboo blocks do not generate inside of bonus chests

Closely relates to MC-250099 and MC-256504.

The bug

As was mentioned in MC-257428, bamboo blocks are effectively the "logs" of the bamboo "wood" set. However, unlike logs, they will never appear inside of bonus chests.

How to reproduce

1. /place feature minecraft:bonus_chest
2. Repeat as many times as is desired
3. Check the contents of each chest

Expected results

Bamboo blocks would eventually appear inside of a chest.

Actual results

They do not.
