Update sqlserver.bicep to use the cheapest SKU by default

[danuw]

When deploying todo-csharp-sql-swa-func using azd up, SQL server instance is on general pricing at £200 a month. This should align with the other free/cheap SKUs used for other resources at £3.50 a month)

This is important to save costs during development.
In addition, is there a way to set the SKU variables by environment?
For example:

// dev
"sku": {
  "name": "Basic",
  "tier": "Basic",
  "capacity": 5
}

// test
"sku": {
  "name": "Standard",
  "tier": "Standard",
  "capacity": 10
}

// prod
"sku": {
  "name": "GP_Gen5",
  "tier": "GeneralPurpose",
  "family": "Gen5",
  "capacity": 2
}

You should be able do using the template parameters for that but I am quite surprised the default is not set to the cheapest option... Especially since Static app is set to free. That is quite a steep price and does not align with the rest. I hope this gets reviewed and approved soon so others don't get stung without noticing.

I created PR #10 which allows that.

Hi in the last Pr (#12) I converted this to use the AVM module. That uses a development grade SKU:

    "sku": {
        "name": "GP_Gen5",
        "tier": "GeneralPurpose",
        "family": "Gen5",
        "capacity": 2
    },

But I agree this would be better as a serverless SKU more like this (GP_S_Gen5_1):

        "tier": {
           "value": "GeneralPurpose"
       },
       "skuName": {
           "value": "GP_S_Gen5_1"
       },
       "zoneRedundant": {
           "value": false
       },
       "numberOfReplicas": {
           "value": 0
       },
       "minCapacity": {
           "value": "0.5"
       },

I think this is best to do as a new clean PR synced to latest. If you want to do or collab @danuw please let me know. Otherwise I can quickly make it.
