Use worker name without UUID as Solr facet

Prefixing with the UUID means humans are confused when using the frontend, and stripping the UUIDs in the frontend requires some ugly hacks. There are two options to avoid it:

• Use UUIDs entirely, and have the frontend handle them as worker version IDs and display the WorkerVersionDetails component
• Use names, which means we get to filter by worker and not by worker version at all.

The latter option is a lot easier to implement so we'll go with that first…
