[BUG] AASX File Server does not return a profile for /description

[aaronzi]

Describe the bug

The endpoint /description for the AASX File Server returns an empty profiles array: {"profiles" : []}

To Reproduce

Start the service and do a GET-Request on /description

Expected behavior

I would expect to get the following result:

{
  "profiles" : { "https://admin-shell.io/aas/API/3/0/AasxFileServerServiceSpecification/SSP-001"}
}
