feat: add selectUpload config option to ImageBlock

Summary

Currently it is possible to configure an onUpload method for the ImageBlock component. This allows you to upload the selected image and return the URL. For our application we already have a collection of images available and it would be nice if the user could also select an image instead of always uploading a new one.

For this I added an selectUpload method which can be configured for the ImageBlock component. This expects a Promise as return value, which works similar to the onUpload configuration option but does not pass a file. Hopefully this is useful for others as well.

How did you test this change?

Since the implementation for this can vary a lot for each implementation, I added a Storybook story to demonstrate the behavior.
