The test tenant_migration_timeseries_retryable_write_retry_on_recipient.js is based off tenant_migration_retryable_write_retry_on_recipient.js which does not run the shard merge protocol due to the stepup in the test.

We should therefor apply that same logic (or use the incompatible_with_shard_merge tag) to not run a shard merge on this test as a temporary solution until we can provide a proper fix.
