[SNOW-1297195] Add tox to daily jenkins job, fix tox.ini. (#1442)

   There were a few issues which prevent the daily snowpark pandas API jenkins job to run successfully:
      - tox.ini had `MODIN_PYTEST_NO_COV_CMD` missing
      - the jenkins invocation script requires tox to be installed
      - the tox_install_cmd.sh was using sh, but should be bash and variables were not defined.
   this PR addresses these issues.
