[Bug] Type TooltipContent is not exported by module @deck.gl/core

Description

If you want to add your own tooltip provider via attribute getTooltip to a Deck, you need to import the types PickingInfo and TooltipContent because getTooltip has the following signature:

getTooltip?: ((info: PickingInfo) => TooltipContent) | null;

While PickingInfo is properly exported by module @deck.gl/core, the type TooltipContent is not exported. The workaround is to import it from the declaring file like this:

import { TooltipContent } from '@deck.gl/core/lib/tooltip';

Although this import works, it actually breaks the module idea of Typescript.

Logs

No response

The public entry point is modules/core/src/index.ts, while TooltipContent is declared in modules/core/src/tooltip. Start by comparing the core exports with the existing import workaround. Done means TooltipContent can be imported from @deck.gl/core and remains usable in the getTooltip signature.
