Get-AzSqlServerFirewallRule firewallrulename wildcard filtering returns all IP rules

[DavidAtImpactCubed]

Description

The docs suggest that you can filter firewall rules with a prefix and a wildcard:
https://docs.microsoft.com/en-us/powershell/module/az.sql/get-azsqlserverfirewallrule?view=azps-6.5.0#example-2--get-all-rules-for-a-server-using-filtering

When using this syntax, all firewall rules are returned, even those that don't match the prefix.

Steps to reproduce

Get-AzSqlServerFirewallRule -ResourceGroupName "ResourceGroup01" -ServerName "Server01" -FirewallRuleName "Rule*"
