Better charts in BlackboxGlobalOptimization.jl benchmark

Is your feature request related to a problem? Please describe.

This benchmark was shown at JuliaCon 2025 in Chris talk about CFD surrogate models (https://youtu.be/PfRxU2kMysU?feature=shared&t=4035), great talk!

It's from this benchmark: https://docs.sciml.ai/SciMLBenchmarksOutput/stable/GlobalOptimization/blackbox_global_optimizers/

In this plot it is impossible for me to distinguish some of the lines due to R/G color blindness (for context: about 1 out of 12 men have the same issue).

Describe the solution you’d like

For the other benchmarks this is not a problem because they use line symbols like this:

The BBO benchmark uses a different plotting setup. So my suggestion would be to just copy the setup that the other benchmarks are already using.

It's a simple fix so I wanted to make a PR, but I can't get the benchmarks to run on my machine so I made this issue instead.

Maybe just use Plotly / Bokeh or any other interactive option which allows clicking on the legend to select a sub set?
Even with the markers added once more solvers are added the graph will be hard to infer from.
