tmux: upgrade 3.6b -> 3.7

Changes:
- Add floating panes: non-modal panes that sit above the tiled layout,
  created with the new new-pane command (bound to * by default). Early,
  currently limited release (move/resize via mouse only).
- Allow run-shell arguments after the shell command to be expanded as
  #{1}, #{2}, and so on.
- Add -g to kill-session to kill all sessions in a session group.
- Add line numbers in copy mode via the new copy-mode-line-numbers option
  (off/default/absolute/relative/hybrid) plus matching styles.
- Tighten read-only checks on attach-session, detach-client and
  switch-client; various control-mode and paste-detection fixes.
