For some reason the metadata of the .ipynb files stay .net C# specific, and I need to edit them, so it would look like this:

"metadata": {
  "kernelspec": {
   "display_name": ".NET (PowerShell)",
   "language": "PowerShell",
   "name": ".net-powershell"
  },
  "language_info": {
   "file_extension": ".ps1",
   "mimetype": "text/x-powershell",
   "name": "PowerShell",
   "pygments_lexer": "powershell",
   "version": "7.4"
  }
 }
