Ensure that matching pair highlights are distinct

With `gruvbox` themes, `{ modifiers = ["reversed"] }` makes it
impossible to identify which pair the cursor is on. `ui.cursor.primary`
is set to be the same as `ui.cursor.match`.

Using `{ bg = "bg2" }` for `ui.cursor.match` makes sure that it is
possible to find out the current cursor position.
