TS example for @mui/styled-engine-sc points to a JS codesandox

[delijah]

Steps to reproduce

Link to live example: https://github.com/mui/material-ui/tree/master/examples/material-ui-cra-styled-components-ts

Steps:

1. Open the codesandbox, and you will see, that there are only js files, instead of ts files, used inside of it.

Current behavior

Only js files in ts codesandbox project (linked on https://github.com/mui/material-ui/tree/master/examples/material-ui-cra-styled-components-ts)

Expected behavior

Ts files only in ts codesandbox project

Context

We try to provide an example to report another bug (and want to use this codesandbox as a basis)
