Passing inputRef to TextFieldsProps breaks MuiOtpInput

[sadik-malik]

When using the MuiOtpInput component and passing an inputRef within TextFieldsProps, the component breaks, the component doesn't accept input anymore. This appears to be due to an incompatibility with how inputRef is handled in the underlying TextField.

Steps to Reproduce:

1. Import and use the MuiOtpInput component.
2. Pass an inputRef through the TextFieldsProps to control the input programmatically.
3. Type anything from keyboard, the TextField component will not accept input anymore.

Expected Behavior:
Passing an inputRef to TextFieldsProps should allow for standard usage and programmatic control without breaking the MuiOtpInput component.

Possible Solutions:
Adding a fork ref behaviour to the component should fix the issue.
