Change how we paginate the query for projects

[Asupkay]

From @ryley-o

I think TheGraph limits skip to a maximum of 5000 items (last I checked).

I know we don't have even close to 5k projects yet, but can we follow the recommended pattern shown in their docs to paginate through projects, along the lines of:

projects(first: 1000, where: { id_gt: $lastID })
