[Radio]: inputProps no longer being applied after introduction of slotProps

[kgregory]

Steps to reproduce

Steps:

1. Open this link to live example: MUI Standalone Radio Button Demo
2. Observe that aria-label is applied via inputProps, but the radio's input has no accessible name
3. Change the dependency to 6.4.5
4. Observe that aria-label is applied via inputProps, but the radio's input has an accessible name

Current behavior

6.4.6 introduced a bug that can be seen in the Standalone Radio Buttons demo: inputProps are no longer being applied:

      <Radio
        checked={selectedValue === 'a'}
        onChange={handleChange}
        value="a"
        name="radio-buttons"
        inputProps={{ 'aria-label': 'A' }}
      />

The radio button no longer has an accessible name. The user needs to use slotProps.input, but that is a breaking change.

Worth noting that this issue is not present in Checkbox and similar treatment for Radio is likely to fix the issue.
