Update compat and remove redundant fixed

[JoeyT1994]

This PR updates the compat on ITensorNetworks and Graphs to more recent versions and removes functions in fixes.jl which were addressed by the PRs in ITensor/ITensorNetworks.jl#195 and ITensor/ITensorNetworks.jl#194

Looks good besides formating, some requests/questions:

• Can you bring the workflows up to the current version in here too? (see e.g. ITensors.jl, using actions/checkout@v4 )
• Do we want to add the dependabot?
• currently using fixes.jl fails for Julia 1.11.0 (they have an open bug about it), any chance we can get rid of it now or overload the add function differently?

[JoeyT1994]

Sure I just bought up the workflows to checkout@v4 and setup-julia@v2 . I also formatted.

Not sure what to do about fixes.jl not working with Julia 1.11.0, do you think they will resolve that issue soon? Quite useful to have a fixes.jl here so we can overload ITensorNetworks functionality with ease -- but I'm open to other suggestions.

Wow that new formatter really screwed up some things. I think I've sorted everything out including the fixes.jl, let me know if everything works on your end and then I'm good with merging

[JoeyT1994]

Thanks! Yeah no idea what that new formatter version is about. Looks good now though.
