Add link to ui.tab to direct user to external URL when clicked on

Is your feature request related to a problem? Please describe

I have a bunch of tabs which I use for navigation. I want the last one to link to documentation which is an external URL. However, I don't see a way to open an external URL using a tab.

Describe the solution you'd like

Ideally, the ability to specify an external URL in the tab, maybe a property called link just like a button.

Describe alternatives you've considered

For now, external URLs were opened by setting inline script to f'window.open("{external_url}");'. However, this is not ideal since the page has to be re-rendered. Do mention if there are any more elegant solutions to this.
