az containerapp create --yaml: issue with userAssignedIdentities

[Trueber]

Describe the bug

az containerapp create --yaml does mess up the resource group and user assigned identities if they contain - or _.

The id
/subscriptions/my-subscription-id/resourcegroups/my_resource_group_dev/providers/Microsoft.Managedidentity/Userassignedidentities/my-user-assigned-identity

somehow gets changed to

/subscriptions/my-subscription-id/resourcegroups/myResourceGroupDev/providers/Microsoft.Managedidentity/Userassignedidentities/My-User-Assigned-Identity

on is then now found

Related command

az containerapp create
