Set the default value of `emacs-mcx.cursorMoveOnFindWidget` as `true`

[whitphx]

One of the most frequently asked question is about emacs-mcx.cursorMoveOnFindWidget, and setting it as true may be more intuitive for most users, from my personal observation. It also aligns other defaults such as emacsLikeTab = false and strictEmacsMove = false in that they keeps native VSCode behavior just assigning Emacs-like keybindings to existing VSCode movements.
