Provide grouping or sliders to make it more obvious on the front page when extensions were added

[holly-cummins]

When sorting by date added, there's no way to find, say, all the extensions released in the past year, except by clicking and doing a binary search. This could be achieved by having a 'dates between' slider on the filters, or by doing groupings (like what Apple does on file open menu) so there's a section for 'past month', 'past year', '2023', etc.

Another way of doing this would just be to add 'date added' onto the card, but I think that's clutter we don't want.
