fix(ci): add explicit bash shell for cross-platform compatibility in cache-refresh workflow (#9934)

The cache-refresh workflow runs on Linux, macOS, and Windows runners. Commands using bash-specific syntax (like ${{ }} expansions and | multi-line blocks) need explicit shell: bash directive to work correctly on Windows where PowerShell is the default shell.

This ensures all bash commands execute properly across all operating systems.
