Display case-sensitive keybindings for vim commands (#24322)

This Pull Request tackles the issue outline in #14287 by changing the
way `KeyBinding`s for vim mode are displayed in the command palette.
It's worth pointing out that this whole thing was pretty much
implemented by Conrad Irwin during a pairing session, I just tried to
clean up some other changes introduced for a different issue, while
improving some comments.

Here's a quick list of the changes introduced:

- Update `KeyBinding` with a new `vim_mode` field to determine whether
the keybinding should be displayed in vim mode.
- Update the way `KeyBinding` is rendered, so as to detect if the
keybinding is for vim mode, if it is, only display keys in uppercase if
they require the shift key.
- Introduce a new global state – `VimStyle(bool)` - use to determine
whether `vim_mode` should be enabled or disabled when creating a new
`KeyBinding` struct. This global state is automatically set by the `vim`
crate whenever vim mode is enabled or disabled.
- Since the app's context is now required when building a `KeyBinding` ,
update a lot of callers to correctly pass this context.
