Bug: v is bound to Quit but displayed as Select in the list keymap

**Describe the bug**

The `Quit` key binding in the list component appears to have been changed from `q`/`esc` to `v`, while the help text was changed to `v, select`.

However, the binding is still the `Quit` binding, and pressing `v` triggers the quit behavior instead of selecting an item.

This change can be seen in [this commit](https://github.com/charmbracelet/bubbles/commit/e97af08ee293131e7b71f7e3006c06a81a2584b8#r197766602)

**Setup**

* OS: Linux
* Shell: zsh
* Terminal Emulator: kitty
* Terminal Multiplexer: None
* Locale: en_US.UTF-8
* Bubbles version: Latest commit containing this change

**To Reproduce**

1. Create a Bubble Tea application using the Bubbles list component.
2. Use the default list key bindings.
3. Focus the list.
4. Press `v`.
5. The application/list exits through the `Quit` binding.

**Source Code**

The relevant change is:

```go
// Before
Quit: key.NewBinding(
key.WithKeys("q", "esc"),
key.WithHelp("q", "quit"),
),

// After
Quit: key.NewBinding(
key.WithKeys("v"),
key.WithHelp("v", "select"),
),
```

**Expected behavior**

If `v` is intended to select an item, pressing `v` should trigger selection rather than the `Quit` behavior.

Alternatively, if `v` is intentionally a quit key, the help text should indicate `v, quit` rather than `v, select`.

**Screenshots**

Not applicable.

**Additional context**

The field is still named `Quit`, and the surrounding code is still under the `// Quitting.` section. This makes it unclear whether the key was intentionally changed to `v` or whether the key/help text was accidentally changed.

The issue was also raised in the review discussion of the commit:

https://github.com/charmbracelet/bubbles/commit/e97af08ee293131e7b71f7e3006c06a81a2584b8#r197766602

Start by inspecting the list component's default key bindings and the change in commit e97af08ee293131e7b71f7e3006c06a81a2584b8. Confirm whether v should select an item or quit, then make the binding name, key, help text, and surrounding quitting behavior consistent. Reproduce the default list interaction and verify that v performs the intended action.
