### Feedback

The documentation for RedisCache includes examples showing SAS for storage accounts. This is getting flagged as an issue by security tooling. In my case it was because it got installed to a folder backed up to One Drive. But in any case, it should probably use a masked example to avoid being flagged.

Example here: https://github.com/Azure/azure-powershell/blob/9c061715ad92dc5fa61179e6edacb4bc0af665ea/src/RedisCache/RedisCache/help/Export-AzRedisCache.md?plain=1#L29

This get distributed in the `Microsoft.Azure.PowerShell.Cmdlets.RedisCache.dll-Help.xml` file when Az PowerShell is installed.
