Mistake in complementer signature

[dcartermath]

Describe the bug
In the signature of Graph.complementer, the default argument for loops is stated as False, when the default behavior is actually True. (I think the behavior should change to match the signature; in practice I suspect that loops=False is the more common usage.)

To reproduce

import igraph as ig
G = ig.Graph(1)
print(G.complementer().get_edgelist()) #should be the empty list

Version information
Python version 3.12.7, igraph version 1.0.0 installed via pip.

Oh wow, how did that slip through?

(I think the behavior should change to match the signature; in practice I suspect that loops=False is the more common usage.)

I agree, but the decision is @ntamas's.

We can maybe make the argument that this should have been corrected in 1.0.0 as an API-breaking change, but was missed ...

In the end having this function add loops would cause as much confusion as making the breaking change in 1.0.1 instead of 1.0.0
