Expanding navigation properties on alternate keys

Related to https://github.com/microsoftgraph/msgraph-sdk-dotnet/issues/2243

From the documentation at https://learn.microsoft.com/en-us/graph/api/directoryrole-list-members?view=graph-rest-1.0&tabs=http#example-2-get-the-members-of-a-directory-role-using-roletemplateid

It should be possible to list the members of a directoryRole using id or using the roleTemplateId alternate key.

GET /directoryRoles/{role-id}/members
GET /directoryRoles(roleTemplateId='{roleTemplateId}')/members

At moment we do not expand paths with alternate keys even though they may have contained navigation properties. As these maybe be valid paths, we will need to investigate the validity and impact on path expansion across other paths.

ファイルやテストは指定されていません。まず path-expansion logic の場所を特定し、id path に対する navigation-property expansion を alternate-key directoryRole examples と比較します。次に、他の paths における有効性と影響を評価します。サポートされる alternate-key navigation paths が定義され、適切な検証でカバーされれば完了です。
