Wrong type definition for Tooltip - content prop

[gguidotti]

Detailed description

Describe in detail the issue you're having.
When using the Tooltip component, if I use a function as the "content" prop (eg. <Tooltip content={() => renderSomething()} />) I get a warning about expecting a ReactNode type and getting a function instead. I believe this should be covered since even the Tooltip component itself contains a check about the type of "content" prop being a function or not (https://github.com/wfp/designsystem/blob/next/src/components/Tooltip/Tooltip.js#L109).

Is this issue related to a specific component?
Tooltip

What did you expect to happen? What happened instead? What would you like to see changed?
Enrich type definition by adding "function" type.
No warning shown.
