Back to search results from a public recipe

[graceliching]

There's no navigation to go back to search results from a public recipe page -- this is on our platform as well, but it's more obvious an issue in the embedded UI.

We should show ''< Back to Community recipes" on the top left in the usual breadcrumbs style.

There are 2 ways users can land on this page:

1. Search: Here, the link will take them back to the search results
2. Direct link: The link will take them to the main community page
