sway: 1.6.1 -> 1.7

Release notes: https://github.com/swaywm/sway/releases/tag/1.7

Notable (backward incompatible) changes:
- The default terminal changed from Alacritty to foot

Known issues:
- `swaynag` will crash when Sway 1.6.1 is still running while the Nix
  package (and thus `swaynag`) is already updated to version 1.7.
- The experimental Ozone/Wayland support of Electron apps will be broken
  for a while. Electron version 17 should work but the Chromium fixes
  haven't yet been backported to Electron version 16.

NixOS module: programs.sway.extraPackages: The "alacritty" package was
replaced with "foot".

VM test: We switched from the OpenGL ES 2.0 renderer to Pixman. The
terminal was also changed to foot but Alacritty is still used for the
XWayland test (since foot doesn't support X11).
