Cycle 2025.1: Search page updates

[ikesau]

Simplifying search now that the data catalogue exists.

Motivation

We have more data on how our users are (not) using the search page, so we want to remove some unneeded complexity and alley oop better
with the data catalog.

Proposed scope

Figma

Must do

• Remove the tabs
• Remove the explorers section
• Update results to include explorers
• Link to the data catalogue
• Update copy
• Add new accordion sections
• Reduce number of charts results to 20

Technical notes

• We'll be able to remove the explorer-views index after doing this, as the search is the only place that uses it (though we still need the code that generates the records.
• If we have a lot of spare time, we could rewrite the search page to get rid of the react-instantsearch dependency (in the way the data catalogue is written)
