[patch] Simplify loop signature

[liamhuber]

Patches a bug when instantiating multiple for nodes with variations in the output format, and simplifies the for-node signature.

Before:

from pyiron_workflow import Workflow

n = Workflow.create.for_node(
    body_node_class=Workflow.create.standard.Add,
    iter_on=("other",),
    obj=1,
    other=[1, 2]
)

Now:

from pyiron_workflow import Workflow

n = Workflow.create.for_node(
    body_node_class=Workflow.create.standard.Add,
    iter_on="other",
    obj=1,
    other=[1, 2]
)
