## Description

`InterpolateConfig` interface is [declared here](https://github.com/software-mansion/react-native-reanimated/blob/7820ec095de7a719150dc5021561f0b8b0b10f38/src/reanimated2/Colors.ts#L768-L773) as follows:

```ts
export interface InterpolateConfig {
  inputRange: readonly number[];
  outputRange: readonly (string | number)[];
  colorSpace: ColorSpace;
  cache: SharedValue<InterpolateRGB | InterpolateHSV>; // <-- Shared value of non-null type!
}
```

few lines below it is being used:

```ts
export function useInterpolateConfig(
  inputRange: readonly number[],
  outputRange: readonly (string | number)[],
  colorSpace = ColorSpace.RGB
): SharedValue<InterpolateConfig> {
  return useSharedValue({
    inputRange,
    outputRange,
    colorSpace,
    cache: makeMutable(null), // <-- returns shared value of null type
  });
}
```

This caused `yarn type:generate` command to fail (it is launched by `createNPMPackage` script):

## Changes

* Modify `InterpolateConfig` interface, so `cache` is of type: `SharedValue<InterpolateRGB | InterpolateHSV | null>`

```ts
export interface InterpolateConfig {
  inputRange: readonly number[];
  outputRange: readonly (string | number)[];
  colorSpace: ColorSpace;
  cache: SharedValue<InterpolateRGB | InterpolateHSV | null>;
}
```



## Test code and steps to reproduce

Run

```
yarn type:generate
```
and see it fails
