adding MinimalApi and Area commands

Adding MinimalApiCommand and AreaCommand (help at the bottom)

MinimalApi has 2 different templates, one supports a DbContext (EF scenario), and one without.
- MinimalApi.tt and MinimalApiEf.tt templates
scenarios covered and tested:
- empty .NET apps (Web App, Web API)
- .NET apps with Individual Auth (this app has EF package references and a DbContext already)
- with and without DbContexts
- new and existing DbContexts
missing scenarios :
- package installation is busted rn due to incorrectly registering MSBuild (fix upcoming soon)
- TypedResult support
- [PrimaryKey] attributed keys and composite primary keys (following the official EF Core docs for primary key discovery) are not yet detected.

minor changes:

updated Microsoft.Build and Microsoft.Build.Locator package versions
remove InteractivePickerType.DbProviderPicker and providing DbProvider selection
rename EfDbContextAnalyzer --> EfDbContextHelpers
added DbSet statement to NewDbContext.tt
