Allow WhenVisible Component to Accept params Alongside data for Enhanced Customization

[HichemTab-tech]

This PR updates the getReloadParams function to allow users to pass both data and custom params when using the WhenVisible component in Inertia v2.

Old Behavior:
Previously, if the data prop was provided, the params prop was ignored. This restricted the user's ability to pass additional parameters when reloading the component, leading to a lack of flexibility.

New Behavior:
Now, the params prop can be used in combination with the data prop. This allows users to extend the request parameters beyond the basic data specification.

• Updated code snippet:

  const getReloadParams = (): Partial<ReloadOptions> => {
      if (data) {
          return {
              only: (Array.isArray(data) ? data : [data]) as string[],
              ...params
          }
      }
  
      if (!params) {
          throw new Error('You must provide either a `data` or `params` prop.')
      }
  
      return params
  }

Use Case:
Consider the following example:

<WhenVisible
    always
    fallback={(
        <SpinnerWithRetry/>
    )}
    data='rooms'
    params={{
        data: {
            lastRoomId: rooms.data[rooms.data.length - 1].id
        },
        onBefore: async (data) => {
            console.log("onBefore", data);
        }
    }}
    children={null}
/>

With this change, both data and params are processed, ensuring that custom params.data like lastRoomId are passed correctly, enabling more flexible and complex reload scenarios.

BTW this can resolve my issue here : #2064

Thanks.
