[pickers] Dependency on ^6.0.0 when MUI-X is supposedly MUI v7 only

[corytam]

Steps to reproduce

Steps:

1. Install @mui/material
2. Install @mui/x-date-pickers

Current behavior

When attempting to install / update material via npm , I get error

I also did a clean reinstall with the latest versions and getting the same issue

Expected behavior

No need to override install with --legacy-peer-deps flag

Context

Based on #16771 , it seems like MUI-X components are to only support MUI v7 . I'm not sure what im doing wrong ,but when i tried to update to MUI v7 , i got issues with x-date-pickers having a peer dependency on v^6

I dug into the files of x-date-pickers and it seems the package.json doesnt reference v7 and matches the peer dependency error above.

For now I am overriding with
npm install --legacy-peer-deps

You are correct that we are aiming to only support material-ui with version 7 or higher with this major release, not the latest. So the support on v7 of MUI-X products should still be v6, and v5.
