### Issue Type?
I'm not sure
### Module Name
avm/res/api-management/service
### (Optional) Module Version
_No response_
### Description
According to [ciphersuite.info](https://ciphersuite.info/), the following cipher suites are considered weak. Should they be disabled in [avm/res/api-management/service](https://github.com/Azure/bicep-registry-modules/blob/main/avm/res/api-management/service/main.bicep) by including them in the `customProperties` or would that have too big an impact on existing users of the module?
