azurerm_mssql_database - support GP_S_Gen5 SKUs up to GP_S_Gen5_40 (

hashicorp#7453)

SKUs for GP_S_Gen5 databases go up to GP_S_Gen5_40 (docs), but the current validator function only allows up to GP_S_Gen5_16. This PR updates the validator to allow all documented serverless SKUs.

This is my first contribution to this, or any Terraform Provider, so please let me know what validation or testing steps I need to do on my end to button up this pull request.
