What this PR does / why we need it: At QDR, we noticed a dataset with ~10K files was not getting indexed by Google. Investigating, we say that Google was failing to read the schema.org information in the page header, apparently due to it's length.
After finding some guidance on an alternate way to provide file download URLs - https://github.com/ESIPFed/science-on-schema.org/blob/main/guides/Dataset.md#accessing-data-through-a-service-endpoint - I went ahead and implemented that approach. It essentially replaces writing a json object per file with one object and a list of fileIds which is significantly shorter.
Subsequent testing at QDR shows that this was effective in allowing Google to index that dataset again.
Which issue(s) this PR closes:
Special notes for your reviewer: posting as a draft in case people want to go forward with it while I'm out. Probably needs a release note about the new jvmoption and doc updates for it. It should probably go in the new https://guides.dataverse.org/en/latest/admin/big-data-administration.html as well.
Suggestions on how to test this: Should be able to set the flag to a low number to trigger the new format with just a few files and could then use Google's tools to verify it can parse the output (I forget which tool/the URL for it).
