Fix Diagram.make_dot for pydot 3.* compatibility

[ethho]

Encapsulates node names and edge attribute attr_map in double quotes before calling to_pydot in method Diagram.make_dot. Partially duplicates changes made in #1176.

Closes #1175 and closes #1169 and closes #1100 and closes #1065. May close related issue #1072.

@ethho This looks good from first glance. I'll try to check this sometime over the weekend/monday to confirm that this works and get back to you on this. Thank you for addressing this so quickly.

Sure thing, thank you @tabedzki for doing the heavy lifting of investigating!

@ethho re-running the same example that I used for #1176, this works without requiring the latest version of networkx.
I wouldn't merge this into my fix as there as my fix requires the latest version whereas this works with current pip versions of both packages and merging it in introduces some key errors due to the extra " in the names. This alternative sidesteps that issue. Your changes also have the added benefits of not needing to update the tests and supporting older versions of Python.

I'd say all that is left is to update the change log and list out all the issues here that this PR closes so clear up some of the backlog. I'll close my PR.

Package versions:
networkx 3.3
pydot 3.0.1
