fix: resolve CI failures on Windows and Linux

Windows fix:
- Update tim2tox submodule to include git repo initialization before
  applying SDK patches. git apply requires a git repository context.

Linux fix:
- Add gstreamer-1.0 development libraries to Linux dependencies for
  audioplayers_linux plugin compatibility.
