[Forecasted Pipeline] Modify grants-ingest.js to account for forecasted fields

[masimons]

In the usdr-gost repo, there is a function called mapSourceDataToGrant located in the grants-ingest.js file.

Add:

const grant = {
  ...
  grantor_contact_name: source.grantor.name,
  grantor_contact_phone_number: source.grantor.phone,
  fiscal_year: source.fiscal_year,
}

grant.forecast_creation_date = milestones.forecast_creation_date
grant.project_start_date = milestones.estimated_start_date
grant.award_date = milestones.award_date

@TylerHendrickson would you mind making sure i'm on the right track here with these mappings? :) Definitely open to chatting about any changes you have in mind
