[MINOR][R] Reorder `Collate` fields in DESCRIPTION file

## What changes were proposed in this pull request?

It seems cran check scripts corrects `R/pkg/DESCRIPTION` and follows the order in `Collate` fields.

This PR proposes to fix `catalog.R`'s order so that running this script does not show up a small diff in this file every time.

## How was this patch tested?

Manually via `./R/check-cran.sh`.
