As part of PM-2933, the team is moving from the DDL shard command classes to the DDL coordinator one the logic to determine whether a user request is targeting an existing timeseries sharded collection.

Such change has effects on the value of the `namespace` field stored in the DDL recovery document as part of the operation identifier, which in case of timeseries collection may contain:

• FCV 6.1: the value of the view namespace
• FCV 6.0: the value of the buckets namespace

The server code (thanks to the modifications introduced by SERVER-68384) is expected to correctly handle the recovery of DDL operations under the following scenarios:

• FCV 6.1 re-executing a DDL request based on a recovery document generated by FCV 6.0 code
• FCV 6.0 re-executing a DDL request based on a recovery document generated by FCV 6.1 code

but we lack the needed jstest to cover this.
