Update for DOLFINx v0.11

[jhdark]

Description

Fix for #1174

Summary

This pull request updates FESTIM to support newer versions of dolfinx and replaces the dependency on adios4dolfinx with io4dolfinx. It also simplifies handling of interpolation points by removing version checks and using the direct attribute access now standard in dolfinx >=0.10.0. The PR updates all relevant dependencies and documentation, and cleans up code that was only needed for older dolfinx versions.

@jorgensd I was running into some issues getting the solver to work in a case with a blocked system of 1 block, i.e. when we have a discontinuous case with a single volume. It seems some new logic was added to make things more efficient when possible, and it wouldn't assign block data. Although I found this neat little fix. What do you think?

[jorgensd]

I have also stumbled upon the 1-block being not blocked issue when I made irksome, and also added a workaround. I'll have a look at this PR sometime this weekend and see if the fix is the same.
