Document the Jenkins object storage sync process

[franTarkenton]

A jenkins process has been setup to sync data between object storage and our on prem SFP. The jenkins pipeline config is located here:
https://github.com/bcgov/nr-rfc-climate-obs/blob/main/scripts/bat/ostore_push.jenkins

Jenkins job config is here: https://apps.nrs.gov.bc.ca/int/cron/job/RIVER_FORECAST_CENTER/job/climate_obs_rsync

Should document somewhere (maybe the rfc wiki) how this works. Could be part of a larger ticket where we document how the various github based flows originate from.
