editor: Add CollapseAllDiffHunks docs (#34124)

## Summary

This PR improves the documentation for diff hunk keyboard shortcuts to
make existing functionality more discoverable to users.

### Problem

Users were unaware that pressing **ESC** already collapses all expanded
diff hunks through the existing `Cancel` action. The functionality
exists but lacks discoverability:

- The `Cancel` action description was too generic: "Cancels the current
operation"
- No documentation existed for diff hunk keyboard shortcuts in the Git
docs
- Users would naturally expect a dedicated keybinding for collapsing
diff hunks

Release Notes:

- N/A

## Diff Hunk Keyboard Shortcuts
When viewing files with changes, Zed displays diff hunks that can be expanded or collapsed for detailed review:
- **Expand all diff hunks**: {#action editor::ExpandAllDiffHunks} ({#kb editor::ExpandAllDiffHunks})
- **Collapse all diff hunks**: Press `Escape` (bound to {#action editor::Cancel})
- **Toggle selected diff hunks**: {#action editor::ToggleSelectedDiffHunks} ({#kb editor::ToggleSelectedDiffHunks})
- **Navigate between hunks**: {#action editor::GoToHunk} and {#action editor::GoToPreviousHunk}
> **Tip:** The `Escape` key is the quickest way to collapse all expanded diff hunks and return to an overview of your changes.
