"Lists" to "Lists & Series"

### Feature Request

## Problem / Opportunity

The refactor proposed is a change on label tag on the search label for Lists. Targeted for every user

This will avoid misunderstanding on Patrons about where to look for Series. Right now Patrons can find Series when selecting Lists on the search bar without really knowing that's where they need to look.

It will get easier for patrons to look for series on the search filters
## Proposal

Change search label from "Lists" to "Lists & Series"
