feat(react): exclude number from keyof JSX.IntrinsicElements (#42282)

It's required to exclude `number` type from `keyof JSX.IntrinsicElements` because of the case when `JSX.IntrinsicElements` has some additional declarations with indexer type, for example

```
declare namespace JSX {
    interface IntrinsicElements extends JSX.IntrinsicElements {
        [name: string]: SomeJSXElementType;
    }
}
```
