[Storage Account]: Documentation does not align with linter policies

### Resource Type

Microsoft.Storage/storageAccounts

### Api Version

2023-01-01

### Issue Type

Inaccurate property type(s)

### Other Notes

Documentation: https://learn.microsoft.com/en-us/azure/templates/microsoft.storage/storageaccounts?pivots=deployment-language-bicep specifies a keyPolicy property as part of the properties object. Linter says it does not exist:

### Bicep Repro

_No response_

### Confirm

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

Compare the Azure Storage Account documentation URL with the Microsoft.Storage/storageAccounts 2023-01-01 type and linter behavior, focusing on the keyPolicy property. Determine which definition is authoritative, then update the affected documentation or type source so the documented properties and linter agree; verify the result against the reported resource and API version.
