[docs] Remove legacy team page

[mnajdova]

One of #27825

Removes the legacy team page and adds a redirect from the old one to the new about us page.

Preview link: https://deploy-preview-28646--material-ui.netlify.app/

Should we instead of removing this add a link to the About us page? cc @danilo-leal @oliviertassinari

Or, maybe it makes sense to keep the team section, one per product, e.g. https://reactjs.org/community/team.html. We could add one for MUI X, once we split the docs. No real preferences.

That would be even better. I like their short bio for each member 😄 But for now, maybe a link to the About us page would be enough. Feels weird to have it only on the landing page.

[danilo-leal]

The team section on the About page is company-wide, which works for now. Whenever and if we split the docs, having one per product is indeed a nice thing because people can reach out to the specific team members that maintain Core, X, and so on. :)

Alright, will add it and leave this open for future reference

[oliviertassinari]

So to be clear, from what I understand, the plan is to:

1. remove the current page duplication (this PR)
2. add the team pages back once its clearer in the docs that we have different products, one per product/team cc @mui-org/x

It sounds great
