Save figures in PDF format

[wassimmazouz]

Suggestion to add a "Download plot as PDF" option in the HTML output results generated by Benchopt. The ability to download the plots in a high-quality format like PDF would make it easier for users to include the results in reports, presentations, and publications.

In addition to this, it would be helpful if there was an option for the plots to contain a legend for plotted solvers.

Thank you for considering this feature request!

That would be a great feature! +1 if someone want to give it a try.
