fix(docs): Use a shared type for service usage balances values DEV-954 (#6233)

### 📣 Summary
Use an unified type for the service usage balance data across
organization service usage responses and service usage responses.

### 👀 Preview steps
1. Access to the kpi bash shell
2. Run the script `./scripts/generate_api.sh`
3. Review that Orval generated the file
`jsapp/js/api/models/serviceUsageBalanceData.ts` and it is imported in
`jsapp/js/api/models/organizationServiceUsageResponseBalances.ts` and `
jsapp/js/api/models/serviceUsageResponseBalances.ts`
