Custom Command: supports keybinding registration

[abeatrix]

CLOSE #3202

• All custom commands will be registered as a VS Code command that can be found in the Keyboard Shortcuts editor
• Added keybinding registration for custom commands in the CustomCommandsManager class

This allows custom commands to be executed via custom keybindings in VS Code.

Also added related docs and walkthrough page.

Test plan

1. In your cody.json file, create a custom command
2. Save the cody.json file
3. Open the Keyboard Shortcuts editor
   
4. In the Keyboard Shortcuts editor, search for cody.command.customn.{NAME_OF_YOUR_COMMAND}
5. Click on the + icon next to the command to assign a custom keybinding for your custom command

“register” is a very generic property name, which could mean anything. Perhaps “allowKeybinding” is more suitable? Also does this property make sense for Jetbrains, or is it very VS Code specific?

Instead… why don’t we just register all custom commands by default?

Jetbrains supports custom keymap as well so i'd assume yes? It will not break Jetbrains as well since the register command is also supported in agent, with tests in agent to cover.

I thought about registering all custom commands but i'm not sure if that'd be a good idea for users that have 1000 custom commands.

Do we support 1000 custom commands? I think that is beyond our design specs.

I'd suggest we register them by default and do away with the config — it's one less config to document, discover, etc.

Makes sense, will update the PR tomorrow to reflect this!
