Update list of tools

[gdalle]

1. Go through the list of Julia packages and Julia-related repositories starred by GitHub user Guillaume Dalle (@gdalle).
2. Filter them to keep only those that are generic development, performance or code analysis tools, as opposed to application-specific packages. Example: Chairmarks.jl is relevant (for benchmarking), but Flux.jl is not relevant (for deep learning).
3. Filter them again to keep only the ones that are not yet mentioned on the blog modernjuliaworkflows, hosted in the present repo.
4. Open a pull request adding these new tools to the relevant pages of the blog.
5. Tag @gdalle for review.

This is an experiment for Copilot
