Find a way to add a link to examples

[Barbapapazes]

In a repo, there may be a folder named examples. In the documentation, we need to find a way to add some links to it like in aside or in footer.

I am thinking to if possible, embed examples in a webcontainer but linking to repo is also good idea 👍🏼

(main thing is that we should make it opt-in strictly. because not always examples are ready/polished enough for end-users)

Now we are under less pressure, PR is welcome to enable as opt-in feature to try 👍🏼
