Add comparision chart between refine and others (e.g. react-admin)

[nimo23]

I'm currently considering whether to use refine or react-admin.

After reading https://marmelab.com/blog/2023/07/04/react-admin-vs-refine.html, I'm leaning toward react-admin over refine, as react-admin seems (still) superior in many respects.

Currently, I believe that many readers of https://marmelab.com/blog/2023/07/04/react-admin-vs-refine.html consider react-admin to be superior and will therefore choose react-admin, even though many points may no longer apply now or in the future.

However, I don't know if many of the points mentioned no longer apply, as refine is being improved and developed at a rapid pace.

Therefore:

It would be nice if there was a current comparison table at https://refine.dev/docs/ that was always up to date.
