[infra] Turn literal | (string & {}) to PropTypes.string

[siriwatknp]

From mui/mui-x#19529

Currently if the type is 'some' | 'value' | (string & {}), the generated prop-types contains object which is not correct:

TestPropTypes.propTypes = {
  operator: PropTypes.oneOfType([
    PropTypes.oneOf([
      "some",
      "value",
    ]),
    PropTypes.object,
  ]).isRequired,
};

The correct code should be:

TestPropTypes.propTypes = {
  operator: PropTypes.string.isRequired,

• I have followed (at least) the PR section of the contributing guide.

Too long 🤣, I can't stand with it anymore.

@brijeshb42 FYI, just pushed b07532a to fix the CI because those ignore are no longer needed anymore because the produced proptypes will always be string.

Nice, been looking into this before as well but eventually abandoned it. Thanks for fixing this.
