operational runscript for pleiades added

[Jourdan-He]

Added in Dandan's C720 pleiades run script under runScriptSamples for GCHP for geoschem/GCHP#271.

Thanks @Jourdan-He. You should also include the environment file and update the README in the directory to give information about the source of the file. Regarding the run script, it does not conform to our new way of using GCHP in 14.0, specifically it does not move and rename the restart file to Restarts after the run or use the appropriate restart file in Restarts based on cap_restart. I think there should be information about that in the README, along with other information provided in the original issue about why the environment is set the way it is.

Thanks @lizziel , I will make adjustments to this PR to include more information you mentioned once Dandan has finished testing.

According to the discussion in geoschem/GCHP#271 (comment) this PR is no longer needed. @Jourdan-He has confirmed.
