Update ProspectRanking and MockDraftPick objects to add new COVID changes related info

[zo0o0ot]

This year, prospect rankings and mock draft picks should have information about whether or not their schools have decided to participate in games this year.

This information should match the property names that are set up in #14 .

For example, ProspectRanking looks like this: https://github.com/Leagify/prospect-scraper-dt2021/blob/0d4a7d59a9a779e1117270b7a0f7622be8a1a931/src/prospectScraper/ProspectRanking.cs#L6-L18

additional properties will likely be:

• fallFootball
• springFootball

Likely, the ProspectMap will also need to have the additional properties. Here's how it looks so far: https://github.com/Leagify/prospect-scraper-dt2021/blob/0d4a7d59a9a779e1117270b7a0f7622be8a1a931/src/prospectScraper/ProspectRankingMap.cs#L8-L29

This is blocked by #19 since schools have changed their minds about when and how to play football this year.
