Duplicate @mui/utils versions installed

[joshkel]

Steps to reproduce

Steps:

1. npm i @mui/material @mui/x-date-pickers @mui/x-tree-view
2. find . -path '*/@mui/utils/package.json' | xargs grep '"version"' | sort -k 3

Current behavior

Three versions of @mui/utils are installed:

• @mui/materials depends on @mui/utils ^9.1.0 (i.e., the current version).
• @mui/x-date-pickers and @mui/x-tree-view depend on @mui/utils 9.0.1 (no SemVer range permitted).
• @mui/x-date-pickers and @mui/x-tree-view depend on @mui/x-internals 9.1.0, which depends on @mui/utils 9.0.0 (no SemVer range permitted).

Expected behavior

If I'm running the current versions of @mui packages, I expect no duplicate @mui dependencies.
