RRT Table: "S" vs "GW" in GCN Circular Link

@keita.kawabe @sushant.sharma-chaudhary

I was fixing GraceDB's public alerts page for O4 and I noticed a discrepancy between the link URL for GCN Circulars between the public alerts page and the RRT table.

Both links have the same URL prefix (https://gcn.gsfc.nasa.gov/other/). However on the public alerts page, the circular file name has the GW prefix, while it begins with S for the RRT table.

Example: for S200316bj, the circular URL is correctly https://gcn.gsfc.nasa.gov/other/GW200316bj.gcn3.

The RRT Table shows the circular URL for S230502m as https://gcn.gsfc.nasa.gov/other/S230502m.gcn3.

Is this an oversight in the RRT table or a change for O4 that I need to reflect in the public alerts page?
