Fix T103719: missing shortcuts info for some tool-settings

Tool settings can be accessed from both `tool_settings` &
`scene.tool_settings`.

As of [0] `scene.tool_settings` was used instead of `tool_settings`
causing the snap shortcut not to display.

Resolve by supporting variations of data-paths so both are detected.
