Update prepare_setRenderEnvironment.sh file.
    
    - Previously, prepare_setRenderEnvironment function was using
      tcar_checkRepoDirSource to verify the absolute path of the directory
      used as source location of configuration files.
      tcar_checkRepoDirSource uses the installed repository as source
      location which make any directory verification in the workplace to
      fail through it. This update changes the function name from
      tcar_checkRepoDirSource to tcar_checkWorkDirSource so the source
      location of verification does be the workplace not the installed
      repository.
