Container Config - document seccomp profile needed to ensure .NET apps run

### Description

I am seeing the following problem when trying to dump the memory using the dotnet-monitor tool:

`{"status":400,"detail":"Write dump failed - HRESULT: 0x00000000."}`

After investigating a bit, and running `./usr/share/dotnet/shared/Microsoft.NETCore.App/6.0.9/createdump -d -v -n 1`, I get:

```
[createdump] ffffffffff600000 - ffffffffff601000 (000001) 0000000000000000 --x-p- 21 [vsyscall]
[createdump] EnumerateElfInfo: phdr 0x562aef77e040 phnum 12
[createdump] ReadProcessMemory FAILED, addr: 0000562aef77e040, size: 56, ERRNO 38: Function not implemented
[createdump] ERROR: ReadMemory(0x562aef77e040, 38) phdr FAILED
[createdump] Target process is alive
```

May you please suggest what are the known requirements for the dump to work?
