swipe: fix swiping onto a new workspace bound to another monitor (#8176) (#9927)

The previous code didn't check if the chosen new workspace was bound to another monitor, causing buggy behavior where workspace was simultaneously open and not.

The fix simply uses `r+1` for new workspace selection.

Also, the previous code would select rightmost workspace + 1, creating large gaps in workspace IDs in some scenarios. Example (`()` and `[]` indicate workspaces on different monitors):

`(1), 2, 3, 4, 5, 6, 7, 8, 9, [10]`

Swipe right on `()` monitor would create:

`(1), 2, 3, 4, 5, 6, 7, 8, 9, [10], (11)`

But with this commit:

`(1), (2), 3, 4, 5, 6, 7, 8, 9, [10]`
