Use `id` as proxy for sorting by `created_at` in Explore Groups Vue
Sort by `id` instead of `created_at` on the Explore Groups (Vue)
https://docs.gitlab.com/development/sql/#ordering-by-creation-date-created_at
This is necessary to fix the performance issue with sorting by creation date. There are currently no index for both `created_at` and `updated_at`. There's a couple of attempts to add index for these but were rejected due to the maximum index limit violation on the `namespaces` table.
We'll undo this proxy once we fix the performance issues with the said columns in https://gitlab.com/gitlab-org/gitlab/-/work_items/588691+
### Implementation Guide
1. Use `id_desc`/`id_asc` when sorting by creation date in the Explore > Groups Vue page
