feat/popover

Implements the Popover widget. The popover is already ready, but in the example I want to add an Input, which is not ready yet. Will merge after integrating the Input widget

• [x] Double check the style before merging

Random: I would recommend using the Figma Shadcn Presets for getting the internal stylings. instead of digging through source code. https://www.figma.com/community/file/1203061493325953101

@dickermoshe the figma is not updated with the last changes unfortunately

Dang it. That was the source of truth for the default text theme. I'll need to confirm their values later
