[material-next][InputAdornment] incorrect import unstable_capitalize from @mui/base/composeClasses

[MarcosBustamante]

The InputAdornment is trying to import the unstable_capitalize from @mui/base/composeClasses:

material-ui/packages/mui-material-next/src/InputAdornment/InputAdornment.js

Line 7 in 797693f

unstable_capitalize as capitalize,

It is generating this annoying error:

Please, update it to upload this function from utils or from the correct source

import { unstable_capitalize as capitalize } from '@mui/utils';
