TeX in docstrings causes DeprecationWarning.

[drj11]

Describe the bug

On Python 3.11 when i import hypernetx i get a few warnings:

>>> import hypernetx as hnx
/Users/drj/prj/HyperNetX/hypernetx/algorithms/homology_mod2.py:1: DeprecationWarning: invalid escape sequence '\{'
  """
/Users/drj/prj/HyperNetX/hypernetx/algorithms/homology_mod2.py:544: DeprecationWarning: invalid escape sequence '\m'
  """
/Users/drj/prj/HyperNetX/hypernetx/algorithms/homology_mod2.py:737: DeprecationWarning: invalid escape sequence '\{'
  """
/Users/drj/prj/HyperNetX/hypernetx/algorithms/laplacians_clustering.py:42: DeprecationWarning: invalid escape sequence '\g'
  """

These are causes by the TeX code appearing inside Python docstrings. Probably the simplest approach would be to make the docstrings raw by changing """ to r""" at the beginning of the affected docstrings [edit: as has been done in s_centrality_measures.py for example].

In addition the affected docstring in laplacians_clustering.py looks like it needs some dollar signs, but i am not familiar with your post-processing documentation tools.

Whilst i found this during my review for JOSS, i do not require it to be fixed for acceptance.

Environment (please complete the following information):

• macOS Darwin 20.6.0
• Python 3.11.4 (main, Jun 20 2023, 16:52:35) [Clang 13.0.0 (clang-1300.0.29.30)] on darwin
