✨Tabs: controlled mode

[oddvernes]

resolves #3022

The feature request was to fix the active prop on <Tabs.Tab> so it could be used to manually set active tab when using tabs as router links, however this proved difficult due to how the internal logic controls the active state. So instead I opted to implement it the way MUI does it by having a value prop on <Tabs.Tab> that sets the active tab if it matches the value sent into activeTab.
I also created a storybook story with a practical example using react-router-dom

It's an improvement for sure.

I see that the active property still exist on Tab component. What stops the next person for trying to use it the way I did?
Should it be removed? Is it possibel to remove it?

I put an /** @ignore */ on it so at least it doesnt show up in the documentation. It is used internally, controlled by TabList
