Support Line Breaks in Tooltip Component Title

Is your feature request related to a problem? Please describe.
Yes, currently the Tooltip component in react-native-paper does not support line breaks within its content. This limitation makes it challenging to present information that's inherently structured in multiple lines, such as addresses or lists, leading to decreased readability.

Describe the solution you'd like
I'd like the content of the Tooltip component to recognize and render newline characters (\n). Alternatively, the component could support styled content that can be formatted with line breaks.

Describe alternatives you've considered
A possible alternative might be to use a custom tooltip component or another library, but it would be more beneficial and coherent to have this feature natively in react-native-paper.

Additional context
Allowing line breaks in the Tooltip component would greatly enhance its versatility. As UI/UX design evolves, presenting content in a clear and readable format is essential, and this change would cater to a wider variety of use cases.
