Boat with chest inventory names no longer are suffixed with 'with Chest'

In Minecraft 1.21.1, opening a boat with chest's inventory would show a title matching the item used to place that chest boat. For example, 'Oak Boat with Chest' would be shown.

However, starting in Minecraft snapshot 24w36a, this inventory name is now only 'Oak Boat', leaving out the chest part entirely, despite the inventory ostensibly being for that chest. This seems like an unintentional change given that it was not mentioned in the changelog for Minecraft snapshot 24w36a.

Relates to MC-276573, which was also a side effect of this change.
