Support for Repository Definition in RequiredModulesFeature Request

Summary of the new feature/enhancement

Currently, all modules are assumed to come from a single repository on Install. I would like to be able to define a repository name for any module objects listed in the RequiredModules array of the manifest so PowerShellGet knows where to find them when they are hosted in different places.

Proposed technical implementation details (optional)

RequiredModules = @(
  @{ModuleName="MyDependentModule"; ModuleVersion="2.0"; Repository="PrivateRepo"},
  @{ModuleName="PublicDependentModule"; ModuleVersion="1.0"; Repository="PSGallery"}
)

Optionally, if I could define just RepositoryUrl and not need to register a repository, that would be another helpful use case.

Duplicate of https://github.com/PowerShell/PowerShellGet/issues/356.

阅读链接的重复 issue #356，然后追踪 Install 如何在 PSResourceGet 仓库中处理 RequiredModules。完成的标准是模块条目可以如图所示选择自己的 Repository，并且 RepositoryUrl 这一替代方案得到澄清或支持；根据项目现有的测试覆盖率确认该行为。
