Please update docs for network firewall policy rule update to reflect correct protocols

Hello,

I recently found an issue with the docs on this page: https://docs.microsoft.com/en-us/cli/azure/network/firewall/policy/rule-collection-group/collection/rule?view=azure-cli-latest#az_network_firewall_policy_rule_collection_group_collection_rule_update

**--protocols**
`Space-separated list of protocols and port numbers to use, in PROTOCOL=PORT format. Valid protocols are Http, Https.
--remove`

In the portal, in addition to Http and Https it is possible (and needed) to add Mssql as a valid protocol to a Firewall Policy Rule Collection.

Despite the documentation, I ran the command including Mssql protocol and it worked.
`az network firewall policy rule-collection-group collection rule update --collection-name MyCollection --name AllowAKSMicrosoft --policy-name MyPolicyName --rcg-name DefaultApplicationRuleCollectionGroup --resource-group MyResourceGroup --protocols Https=443 Mssql=1433`

However, the corresponding [Terraform module in azurerm provider](https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/firewall_application_rule_collection) only accepts Http and Https.

**Request is to review and update the docs, so that Terraform implementation can match it.**

Hope it helps,

Best regards,

-Luis
