[Modules] Leave out not supported throughput field in Cosmos

[itpropro]

Description

When CosmosDB is deployed serverless, it is not supported to provide throughput.
Therefore a filter was introduced in the options to conditionally provide the property.

...
    options: contains(databaseAccount.properties.capabilities, { name: 'EnableServerless' }) ? null : {
      throughput: throughput
    }
...
