members subresource is missing under directoryRolesWithRoleTemplateId in 6.5.1

The Graph API supports listing members of a DirectoryRole via both its role-id and its roleTemplateId, like can be seen here: https://learn.microsoft.com/en-us/graph/api/directoryrole-list-members?view=graph-rest-1.0&tabs=http#http-request

In the new SDK, this would translate to these two statements:

client.directoryRoles().byDirectoryRoleId("roleId").members().get()
client.directoryRolesWithRoleTemplateId("roleTemplateId").members().get()

Of these, the first works fine, but the second is missing. DirectoryRolesWithRoleTemplateIdRequestBuilder does not have a members() method. In the Graph API, both constructs should behave identical, both for querying and manipulation (for example adding new members). The absence of this method forces us to split the call in two: first get the directory role by template id and then perform the actual operation.

Start with DirectoryRolesWithRoleTemplateIdRequestBuilder and compare it with the working directoryRoles().byDirectoryRoleId("roleId") builder. Trace how members() is exposed for the role-id path, then verify that the template-id path supports the same querying and member-manipulation operations. Done means client.directoryRolesWithRoleTemplateId("roleTemplateId").members().get() and the corresponding operations are available.
