Use default nbt when parsing blocks

[SirYwell]

Overview

Fixes #2944

Description

Not setting the block with its default NBT data results in the (vanilla) client not rendering the blocks properly. We should also probably pull upstream changes in that area at some point, but that didn't look as straightforward as this fix.

Looks good I guess.
I think we should apply upstream changes rather sooner than later, so that NBT data can be specified as well - so that would probably address that as well, kind of (https://worldedit.enginehub.org/en/latest/usage/general/patterns/#single-block-pattern)
