Add Way for Donors to Indicate When They Want a Charitable Receipt

[mekkim]

In preparation for completing our charitable status formalities with CRA, soon we'll be issuing charitable donation receipts (retroactively to January 2022). In order to issue them, we need some information from donors per CRA guidelines.

Donors do not HAVE to get a charitable donation receipt, and some won't want them. So we should have some way of them flagging that they want one, and if they check that box, prompt them to collect necessary information. I don't yet have the list, but it'll probably be:

1. Full Legal Name
2. Full mailing address
3. Telephone
4. Email

This information should probably pushed into a separate MongoDB Collection in the Donatemask database called something like "Charitable Donation Receipt Information" so that it's partitioned from the rest and kept beyond the deletion policies of other private data, per CRA retention guidelines for issuing donation receipts.
