[eslint-plugin] valid-styles error when using `stylex.firstThatWorks`

### Describe the issue

when using `stylex.firstThatWorks` on a property, I'm seeing ESLint errors for `@stylexjs/valid-styles`

e.g.

```ts
const styles = stylex.create({
example: {
position: stylex.firstThatWorks("sticky", "fixed") // errors, but shouldn't
}
})
```

### Expected behavior

using the above code should work with ESLint Rule

### Steps to reproduce

1. use the example
2. see ESLint showing error, even though the styles are valid.

### Test case
