Pull request template

Describe the purpose of the change, the specific changes done in detail, and the issue you have fixed.
Make Next Queries requests take into account when a query is selected along with a related tag:

• Make NQ storeModule have a RTs array in the state to save the selected RTs
• Make NQ storeModule have a mutation to update the RTs in the state
• Make NQ storeModule have a query getter to concat the query with the RTs (if selected)
• Make NQ request use the query getter.
• Make NQ wiring react to the event SelectedRelatedTagsChanged & call setRelatedTags mutation

Motivation and context

Currently, the Next Queries module doesn’t take into account the selected related tags. This creates some weird scenarios like having NQ when searching for novela negra but not having NQ when searching for novela and then selecting the RT negra

How has this been tested?

Test in CDL:
Use a local build of x-components & env=live to test

• Test: ?env=live&query=novela%20negra
• Test: ?env=live&query=novela + select the “negra” RT
  Then:
• Next queries state has an RT array with the RT saved
• A NQ request has been done & given the same results searching for the full query “novela negra” as searching for “novela” and then, selecting the “negra” RT

👀 We should also make changes to CustomNextQueryPreview component in the archetype to handle the use case of a query + an RT when showing what users have searched for. A task created accordingly.
