Update URL based on selected filters

[davidak]

For example when i click on the tag Ubuntu, the URL can become

https://uses.tech/#Ubuntu

so i can send that link and new visitors will see the filtered page.

Also for multiple filters #585

https://uses.tech/#linux+🇩🇪

What about a page-based approach?

For example: https://uses.tech/ubuntu

Admittedly, I am not very familiar with Gatsby, but I assume there is a way you can call a route [slug].js?
That way, we could have the desired effect.

Caveats:

• I don't see how this would be extensible to combined categories (your example should become https://uses.tech/linux/🇩🇪 but I don't know how this can be achieved)
