Add the github_project_v2 table

[dark-panda]

This PR adds a table called github_project_v2 that contains some of the fields exposed by the GraphQL API for ProjectV2 and adds a few fields to github_issue to allow you to join the two tables together. We're using the github_project_v2 name here rather than github_project because of existing fields in tables like github_team and github_organization that reference projects_v2_total_count and such.

Example queries:

=> select * from github_project_v2 where organization = 'turbot' ;

@dark-panda Thanks for raising this PR! I've added a few suggestions and questions in this PR. A few other minor points:

• Can you please add a table doc page for docs/tables/github_project_v2.md?
• Can you please also update the PR description, which have different (possibly older) columns? I think it'd be helpful to see the results of the example queries from the upcoming table doc.
• Locally, models/project_v2.go and table_github_project_v2.go both fail gofmt -l, can you please check these files?

If you have any questions, please let us know!
