Versioned Examples #20
Description
Would be nice to have examples for each major releases of the library.
A basic way to do this could be to add v5, v4, v3, etc. directories inside of src at the top level and make demos/ and guides/ in each.
This pattern would allow for the urls to look like /v5/demos/fonts/async-await and for different examples to exist for each version.
We could have the current version be toggled with some sort of selector under the examples text in the left sidebar.
