Feat: Share docs for Sbanken themed components 🚀

[langz]

🚀 Feature Proposal

After I've changed the theme to be Sbanken, I would very much like to share the Sbanken themed docs for the Button to a colleague:

But when I copy the URL in the browser, the URL is https://eufemia.dnb.no/uilib/components/button/, and when my colleague opens the link, this is what he sees:

Is it possible to always include/have the query parameter ?eufemia-theme=sbanken included in the URL when changing/swapping theme? So that the browser URL would be https://eufemia.dnb.no/uilib/components/button/?eufemia-theme=sbanken
