fix: ai generation of mindmap fail from note text context (#8952)

Fix issue [AF-1632](https://linear.app/affine-design/issue/AF-1632).

### What Changed?
- Keep the note selection and do not set the widget tool to copilot if asking AI from selection in a note in edgeless mode.
- Remove `content` from `AIImageActionOptions`, using `input` as AI context like other actions.
