Add Fortran elastic-tube-1d solvers

[YonatanGM]

This PR adds Fortran solvers for elastic-tube-1d case using the Fortran bindings (not the Fortran module). I opened another PR #607 with the module approach if you prefer that

The solvers follow the same project structure as the other solvers. LAPACK is needed for the fluid solver (same as the C++ case). Run ./run.sh to compile and execute the solvers via CMake. The plotting scripts (plot-diameter.sh and plot-all.sh) are updated to show results for the Fortran case. The precommit yaml didnt have hooks for Fortran files, so I maunally formatted them using fprettify.

Results look consistent with the other solvers. I checked the VTK output, and the numbers match up to 5 decimal places on the last timestep. Also tested running the fortran case against the other solves and that seems to work fine too.

Results:

Checklist:

• I added a summary of any user-facing changes (compared to the last release) in the changelog-entries/<PRnumber>.md.
• I will remember to squash-and-merge, providing a useful summary of the changes of this PR.
• Update the image used in readme showing diameter and pressure of running all solvers against cpp to inlcude fortran case
