feat(vcs): bind Git › Add to ⌥⌘A / Ctrl+Alt+A (#1159)

Git › Add (vcs.addToVcs) had no shortcut in the IntelliJ keymaps. It now uses ⌥⌘A on macOS and Ctrl+Alt+A on Windows/Linux, so it shows next to Add in the Git menus and works from the project view, editor and Commit view. On Windows the diff viewer's Apply Right Side keeps Ctrl+Alt+A while a diff is focused. The VS Code preset lists the action without a shortcut.

Closes #1158
