Resolves:

Issue: "Suggesting: infinite scroll in Explore #9384", implementing infinite scroll on the Explore page.

Changes:

Here is a video linking to how it looks when run locally:

To preserve the existing API implementation and maintain database security, we created a mock API that uploads randomly generated photos to represent sample projects. Because of this we additionally had to change how our mock cards are passed into the Grid component which is seen in handleGetExploreMore.
Our implementation only modified the "Explore.jsx" file, we added an event listener that is triggered upon user scrolls as opposed to the load button design. This increases user experience on the explore page.

Test Coverage:

A potential reason for the overtime error could be that I ran the program locally on my personal computer rather than on a higher-performing computer.
