Add Separator to top of Explore Page

UI Polish -- Priority: MEDIUM

On Explore page, would be good to separate the campaigns/platforms/instruments section from the data products section, since the data products aren't specific to any one camp/plat/inst.

Suggestion/idea I had: A simple "pipe" symbol between the words at top of explore page might be a simple and effective way to convey this idea:

Hi @smwingo I forgot to comment earlier on this one. After talking through with Tammo, our thoughts here were:

• We aren't sure if it would create clarity by adding a separation. While data products does use a table results view that looks a bit different, the top search UI pretty consistent (all the filters share the same look and behaviour) and it's just another way of exploring metadata in the system.
• When we first started the data products view we discussed whether it should have its own main navigation outside of the Explore section that might have created a very clear distinction. However, we ultimately decided that it was actually fitting within the Explore section as it's just another way you can explore the metadata
• I kind of think the pipe signals a difference and yet it's not super clear what distinction we are trying to communicate.

If you feel strongly for us to move ahead with a pipe between, it should be an easy update. Just wanted to share the comment and see if it's something we can leave out.

@heidimok that sounds good to me -- this was totally just a "from my head" thing and I definitely am open others'/yall's ideas -- this all sounds like grounds to nix the "pipe" idea and keep the look how it is -- thanks!
