When trying to login on KDE Plasma I get an error message when VSCode tries to save my credentials (see screenshot below).
Ideally, VSCode would use KWallet on KDE to save credentials. I know I could install gnome-keyring, but seeing as I'm not using Gnome, I'd prefer not to.

Steps to Reproduce:

1. Click the button to login in VSCode
2. After being directed to the GitHub auth page, authorize the application
3. Get redirected to VSCode again and confirm
4. The message shows up

Translated: "Writing the credentials into the keyring failed with the error ..."
