[core][docs] Remove the "Understanding MUI packages" page

[samuelsycamore]

Understanding MUI packages is very outdated and just generally feels out of place as a doc in the Material UI product space. The products are described better in the Introduction to the MUI ecosystem blog post, and the info about styled-components can also be found in the Using styled-components doc, so I don't think this page really serves much of a purpose.

Here's what I propose:

• remove Understanding MUI packages
• redirect that page to the MUI ecosystem blog post
• update the ecosystem blog post to include package names as well as the latest info from MUI X

@ValkonX33 go ahead and open a PR for the first 2 points on the list! I'll take care of the third part (updating the content of that blog post). Do you know how to add a 301 redirect on the site?

Hey Thnaks
i'm having an issue, i'm not able to redirect the understand-mui-packages.md to mui-product-comparison
i've attached the screenshot of the problem would you mind looking at it and check if i'm doing it right in the understand-mui-packages.js file
its showing module not found i think i'm messing up with path of file which is causing the whole issue

i replaced the original path of understand-mui-packages.md path with mui-product-comparison.md path
