fix(auto-dim): stop the minibuffer from re-dimming the window you leftHEADmain

- Opening the minibuffer dimmed whatever window you had just left.
- Dimming follows selection, and the minibuffer takes selection.
- auto-dim-other-buffers-dim-on-switch-to-minibuffer sat at its package default of t.
- Set it to nil, so minibuffer entry leaves the dim state alone.
