What does this look like on the command line? Other plug-in settings look like this:
```
plugin.dynamic-loader.darwin-kernel.load-kexts (boolean) = true
plugin.dynamic-loader.darwin-kernel.scan-type (enum) = fast-scan
plugin.jit-loader.gdb.enable (enum) = default
plugin.object-file.pe-coff.abi (enum) = default
plugin.object-file.pe-coff.module-abi (dictionary of enums) =
plugin.process.kdp-remote.packet-timeout (unsigned) = 5
plugin.process.gdb-remote.packet-timeout (unsigned) = 5
plugin.process.gdb-remote.target-definition-file (file) = 
plugin.process.gdb-remote.use-g-packet-for-reading (boolean) = false
plugin.process.gdb-remote.use-libraries-svr4 (boolean) = true
plugin.symbol-file.dwarf.ignore-file-indexes (boolean) = false
plugin.structured-data.darwin-log.auto-enable-options (string) = 
plugin.structured-data.darwin-log.enable-on-startup (boolean) = false
```
So hopefully this show up in `settings set plugin.symbolvendor.symbollocatordebuginfod.urls <url1> [<url2>]`
