Side-nav support for URL fragments

[OlliTietavainenVaadin]

Describe your motivation

If you use Side Nav with hashed VueJS routing (https://router.vuejs.org/guide/essentials/history-mode#Hash-Mode), all items are considered current. Use cases like this would need explicit support from Side Nav.

Describe the solution you'd like

You should be able to configure Side Nav to work with hashes instead of full route paths.

If it is possible in Vue to have lifecycle callback similar to updated() in Lit or something similar you can do with React's ref + setTimeout which executes function after render, you should be able to set current attribute in vaadin-side-nav items based on your own logic.
