Add ability to bind to pane::RevealInProjectPanel (#7487)

Previously it wasn't possible to create a keybinding for this action
because it required an argument.

Now the action takes the active item of the pane and if it's a
multi-buffer the first one.

This also adds a default keybinding for Vim mode: `-` will reveal the
file in the project panel.

Fixes #7485.

Release Notes:

- Added `pane::RevealInProjectPanel` as an action in the command
palette. ([#7485](https://github.com/zed-industries/zed/issues/7485)).
