- Supports configuring a custom confirmation prompt via `config.yml` for
custom keybindings. A new `CustomCommandPrompt.Body` field is
used to store the immutable body text of the confirmation popup.
- Adds a sample 'confirm' prompt to the example `config.yml`.
- Updates the `Prompts` section of the documentation to include
'confirm' prompt type and also describe which fields pertain to it
(i.e. `initialValue`).
