Fix T96152: Crash realizing curve instances 

The "curve_type" was transferred to instances because it isn't a
built-in curve attribute. Then it was interpolated as a point
domain attribute from the instance domain in the realize
instances node.

The fix was just missing from 9ec12c26f1.
`curve_type` needs to be marked as a built-in attribute.
