Update the Input Logic of Cell Complex Models

[gbg141]

This pull request aims to update the input logic of cell complex models by

• unifying the nomenclature of connectivity matrices across the different models, in accordance to TopoNetX library (i.e. adjacency_r, incidence_r, down_laplacian_r, etc.);
• adding **kwargs optional parameter to models and layers, hence allowing the flexibility to modify additional parameters of the model's inner layers (standard practice in other libraries such as torch_geometric).

Upon acceptance of these changes, similar modifications will be applied to Hypergraph, Simplicial, and Combinatorial models.

Excellent, thank you very much for this! Green light to update the other files for consistency with toponetx.
