feat(js,react): Export InboxContent component

[desiprisg]

What changed? Why was the change needed?

This PR:

• Exports the <InboxContent /> component which is what is used under the hood to render <Notifications /> and/or <Preferences />. It's usage will be primarily with custom popovers (See example in playground).
• Fixes the custom popover issue of not opening on click, because of the react tree hierarchy (caused by our rendering higher up). This is done via one renderer per component we export in @novu/react.
• Fixes the issue where the custom popover closes because we render something in a portal (thus the popover loses focus). This is done via rendering all dropdowns and tooltips without a portal.
  • Also fixed an issue that appeared because of this, with autoUpdate where the layout was affected in a weird way. Passed options elementResize: false, ancestorScroll: false, animationFrame: false, layoutShift: false to it to fix.

Overall works well, great job! 🙌 Just noticed that the custom popover looks a bit odd.

Yeah I never applied a max height I think, that's why!
