In the NBT of .mcstructure files created from Structure Blocks, upper and lower door blocks both have some block states which are always set to 0.

Specifically, upper door blocks have `direction` and `open_bit` always set to 0; and lower door blocks have `door_hinge_bit` always set to 0.

In 1.21.60.24-preview, the `direction` block state is replaced with `minecraft:cardinal_direction` which is present properly in upper door blocks. However, upper door blocks still have an incorrect `open_bit` and lower door blocks still have an incorrect `door_hinge_bit`.

This hinders the development of third-party tools that interact with structure files in order to generate 3D models based on in-game structures.

In the attachment of this bug report is a structure file from 1.21.60.24-preview, which reveals the incorrect block states.
