azurerm_synapse_workspace naming is incorrect

[JasonKoch]

The project's current model does not allow hyphens and only 45 characters in a Synapse Workspace name. The current published rules say hyphens are allowed and the name may be up to 50 characters. Here is the relevant entry in models_generated.go:

"azurerm_synapse_workspace": { "azurerm_synapse_workspace", "syws", 1, 45, true, "[^0-9a-z]", "^[0-9a-z]{1,45}$", false, "resourceGroup" }
