chore: Omit disableUnderline prop for ‘outlined’ variant, because its…

… not supported.

The `disableUnderline` prop is only available in the `Input` and `FilledInput` variants, not in `OutlinedInput`.

See docs for reference:
- [FilledInput (filled)](https://mui.com/material-ui/api/filled-input/#props)
- [OutlinedInput (outlined)](https://mui.com/material-ui/api/outlined-input/#props)
- [Input (standard)](https://mui.com/material-ui/api/input/#props)
