[FIX] web_editor: allow edition of branded nodes only

To be able to be saved, nodes have to provide information on where to
save them. This is done through the use of data attributes. Nodes that
do not have these data attributes or are not contained within nodes that
do, should therefore not be editable.
Recent changes in Jabberwock ensure that the nodes with these data
attributes are saved either as `OdooStructureNode` or as `OdooFieldNode`
so we can simply check for these.

closes odoo/odoo#63311
