Bump DOCKER_IMAGE_PIN (and the generated linux manywheel binary build
workflows) from f38ba0b10220982e39441d29d203d803a2b56c92 to
78e737ad29420ffc4800e677c51e2a852caf8359, the latest manylinux2_28 /
manylinuxaarch64 builder images built for v2.13.0-rc10.

Verified the new images are published on Docker Hub (e.g.
pytorch/manylinux2_28-builder:cuda12.6-78e737ad..., cpu-78e737ad...).
Equivalent to regenerating the workflows after the pin bump (only the
docker hash changes).
