Diff Tool should ignore positional changes in enums

Related to changes in microsoftgraph/msgraph-sdk-dotnet#2826

The tool does detect the change in order of the enums where the timeCard member is inserted into the enum at position 8.

Removal of Microsoft.Graph.Models.workforceIntegrationSupportedEntities has an enum member timeOffReason with order 8
Removal of Microsoft.Graph.Models.workforceIntegrationSupportedEntities has an enum member timeOff with order 9
Removal of Microsoft.Graph.Models.workforceIntegrationSupportedEntities has an enum member timeOffRequest with order 10
Addition of Microsoft.Graph.Models.workforceIntegrationSupportedEntities has an enum member timeCard with order 8
Addition of Microsoft.Graph.Models.workforceIntegrationSupportedEntities has an enum member timeOffReason with order 9
Addition of Microsoft.Graph.Models.workforceIntegrationSupportedEntities has an enum member timeOff with order 10
Addition of Microsoft.Graph.Models.workforceIntegrationSupportedEntities has an enum member timeOffRequest with order 11

However, from metadata change at https://github.com/microsoftgraph/msgraph-metadata/pull/760/files#diff-eb3d3e370adab9ae29d645852adb1ce71b9206412f026061d55bd4b4b3776d48 the insertion isn't really breaking given that the value members was not set.

We should probably investigate ignoring insertions (the positional order) of enum members in breaking change detections for graph because the members end up being serialized as strings as from the SDK perspective, the change in position is really to be determined by the API.

This would involve changing the serialization of the dom to no longer have the positional parameter as seen here https://github.com/microsoft/kiota/blob/c35b901a90fbd6e19a6790d7fea8ef1ab14a5a35/src/Kiota.Builder/Export/PublicAPIExportService.cs#L80
