azurerm_mssql_database - support min_capacity up to 5 (hashicorp#7457)

Minimum capacities for GP_S_Gen5 serverless databases go from 0.5 to 5 (docs), but the current validator function only allows min_capacity up to 2. This PR updates the validator to allow all documented minimum capacities for serverless databases.
