Add github action to build and run tests about prospect-scraper-dt2021

I can tackle this pretty soon if you wanna throw this to me, I had it building and running test on another branch with github actions, but the upgrade to target .NET 5 kinda messed it up so I'll have to look at it a little bit more.

I know the build failed for me after the .NET 5 upgrade because the project name references had been put into PascalCase even though the file names were in camelCase. I think that probably works in Windows and blows up in Linux. I fixed it in #35, but it would have been nice to catch before I merged the original commit that broke it.

Definitely agree there!

Right now getting this error:
Error: /home/runner/work/prospect-scraper-dt2021/prospect-scraper-dt2021/test/prospectScraperTest/ProgramTest.cs(33,50): error CS0117: 'Program' does not contain a definition for 'FormatDraftDate' [/home/runner/work/prospect-scraper-dt2021/prospect-scraper-dt2021/test/prospectScraperTest/ProspectScraperTest.csproj]
Seems like a method might've been renamed to something else, trying to look through and see what it was changed to unless you know off hand?

Handled in #36
