With #2898 we introduced initial Project V2 features. With the introduction of go-github v78/79 there was a huge push to round out the Projects V2 offerings. We should incrementally implement the following:

Projects resource (github_project)

• CreateOrganizationProject
• CreateUserProject
• UpdateOrganizationProject
• UpdateUserProject
• DeleteOrganizationProject
• DeleteUserProject
• GetByProjectNumber

Project field resources (github_project_field)

• Create, update, delete custom fields
• ProjectV2FieldIteration
• ProjectV2FieldConfiguration

Team Integration (github_team_project)

• AddTeamProject
• ReviewTeamProjects
• ListTeamProjects

Webhook Events

• ProjectV2Event
• ProjectV2ItemEvent
