It's a relatively common occurrence to run out of space for the property name
when using the Attribute Node, making it unreadable. A big part of this space is
eaten up by the labels, especially since the space they take up scales up with
the node width.
It can be argued that the info provided by the labels (`Type:` & `Name:`), are
superfluous and not essential. Removing them does not make the node harder to
use, and frees up more space for the user to type longer property names.
This is quite similar to changes done in #127992 for Geometry Nodes.
