Release: Update Docker Image Pin

Pins the Linux manywheel builder docker images that the binary build workflows in pytorch/pytorch use, so a release branch builds against a fixed, reproducible toolchain instead of the floating tags that main tracks (e.g. pytorch/manylinux2_28-builder:cuda12.6). The pin lives in the workflow generator, so it survives regenerate.sh and the lint "generated files are up to date" check.

This skill operates on a pytorch/pytorch checkout (usually a release/X.Y branch), even though the skill itself lives in test-infra.

Inputs
