### Bicep Repro

}

### Confirm

- [X] I have read the troubleshooting guide and looked for duplicates.

Start by locating the Microsoft.Synapse/workspaces/sqlPools/workloadGroups type definition for API version 2021-06-01 and inspect the minResourcePercentPerRequest and maxResourcePercentPerRequest properties. Confirm the accepted decimal-string values from the Bicep reproduction, then update the definitions so both properties match the API behavior.
