feat: add additional keymap

[Odonno]

Improve experience by adding vscode keymap.
At least for me, it make CTRL+K+C and CTRL+K+U works.

• Add vscode-keymap plugin to add additional keymaps https://github.com/replit/codemirror-vscode-keymap
• Disable mod+K hotkey confitionally (disabled when in-editor) to be able to use CTRL+K+C and CTRL+K+U. Search window still works outside the query editor
• Added hasEditorFocus and setHasEditorFocus in the InterfaceStore

Note: there is a warning to set defaultKeymap: false. I did not make this change and still to work as-is. I am note sure if anything is broken.

I'm absolutely up for adding additional shortcuts and adopting the vscode keymap, however I think it's important for cmd+K to remain working within editors (and everywhere else throughout the app), even if this means we have to drop or preferably remap certain shortcuts

I can understand the point. Better stick with consistency. But it just feels frustrating not to be able to use the common comment/uncomment key bindings, even more frustrating when it opens the command palette.

One idea could be to offer a remapping of key bindings. Kind of what video games offers. But that seems too much effort and code for such a feature.

Another idea that can be simple to do could be to disable command palette (via feature flag) so that we can enable the comment key bindings. It would be trading a feature for another. Not liking it much though.

I'm satisfied if we keep commenting on cmd + / so we can leave cmd + K accessible from editors
