fix(users/multi/home): fix tmux keybindings for tmux 3.1 r/1936

The "swap-window" command swaps two windows, the 'source' and
'destination' window, exchanging the indices they occupy in the window
list. In at least tmux 2.8 (which is what's in Debian Stable), if the
window under focus is the source window, then focus follows that window
(i.e. the focus changes to the current window's new index atomically
with it being moved to that index).

In more recent tmux versions, this is not the case, and the focus
remains on the old index, so that the replacement window comes under
focus. The former behaviour is still possible, but must be explicitly
requested.
