Get-AzRedisCache does not return minimumTlsVersion where "az redis show" does

[devblackops]

Description

The Redis properties exposed with Get-AzRedisCache are not consistent with what az redis show returns. In particular, I'm interested in minimumTlsVersion, which I can't find a way to return with the PS module.

Steps to reproduce

# Observe properties returned with PS module
Get-AzRedisCache -Name $name -ResourceGroupName $rg

# Observe properties returned with az cli
az redis show --name $name --resource-group $rg
