Add Bash/WSL2 support in WinRM steps to enable native Bash execution on Windows hosts, with selectable shell type (PowerShell or Bash), consistent variable handling, and unified logging. This simplifies hybrid automation, eliminates redundant scripts, and unifies cross-platform deployments within a single Harness pipeline.

Harness WinRM currently supports only PowerShell, forcing teams to duplicate scripts or split workflows across Linux delegates.
