Unable to set vscodevim default settings through keymap extension

Describe the bug

• I am writing a VS Code extension lunarkeymap
• The extension is unable to contribute defaults for vscode vim

Here are the error messages:

• Cannot register configuration defaults for 'vim.normalModeKeyBindingsNonRecursive'. Only defaults for machine-overridable, window, resource and language overridable scoped settings are supported.
• Cannot register configuration defaults for 'vim.visualModeKeyBindingsNonRecursive'. Only defaults for machine-overridable, window, resource and language overridable scoped settings are supported.
• Cannot register configuration defaults for 'vim.insertModeKeyBindings'. Only defaults for machine-overridable, window, resource and language overridable scoped settings are supported.

To Reproduce
Steps to reproduce the behavior:

1. Generate new VS Code keymap extension
2. Edit package.json
3. Add new "contribute" object
4. Add new "configurationDefault" object
5. Add

    {
      "before": ["<C-h>"],
      "commands":["workbench.action.navigateLeft"]
    },
     
    {
      "before": ["<C-l>"],
      "commands": ["workbench.action.navigateRight"]
    },
  ],

6. Add the extension locally
7. Test the extension

Expected behavior

• vscodevim is able to be configured via any vscode keymap extension

Screenshots

Environment (please complete the following information):

• Extension (VsCodeVim) version:
• VSCode version: 1.80.0
• OS: Windows and Linux

Start by reproducing the configurationDefault entries in package.json with the listed vim.normalModeKeyBindingsNonRecursive, vim.visualModeKeyBindingsNonRecursive, and vim.insertModeKeyBindings settings. Check the VS Code configuration-scope behavior that produces the reported errors; done means establishing supported behavior and implementing or documenting a clear resolution.
