fix(window): middle separator colors (catppuccin#369)

* fix(window): middle_separator

`middle_separator` is _not_ the same for fill `number` and `all`.
For fill the colors are the same as text or color.

* chore(window): move left inside fill all branch

left_separator was _always_ overwritten in the `fill == number` branch.

Fixes catppuccin#353
