style(Wind): Use POSIX sh shebang for build scripts

Update the shebang line in both Source/Run.sh and Source/prepublishOnly.sh from `#!/usr/bin/env bash` to `#!/usr/bin/env sh` for improved portability across Unix-like systems.

This ensures the build scripts can execute on systems where bash may not be installed or available at the standard path, adhering to POSIX compatibility standards.
