Republish diagnostics on schema change automatically

[radeksimko]

Background

As discovered in multiple issues:

• azuread_service_principal for resource and data resource needs to be updated to support "client_id" vscode-terraform#1621
• Terraform LS 0.32.4 - tfe provider 0.51.0 - tfe_organization data source - LS not accounting for changes that occurred in this version #1523
• Vscode Language Server is preloading wrong provider version - intellisense then not working vscode-terraform#1701

the server currently does not re-publish relevant diagnostics whenever the schema changes, for example, when a provider is installed.

Proposal

We currently refresh various things, such as semantic tokens and this is all done through memdb "hooks" here:

terraform-ls/internal/langserver/handlers/service.go

Lines 491 to 509 in a2e542e

	if _, ok := lsp.ExperimentalClientCapabilities(cc.Experimental).ShowReferencesCommandId(); ok {
	moduleHooks = append(moduleHooks, refreshCodeLens(svc.server))
	}
	if commandId, ok := lsp.ExperimentalClientCapabilities(cc.Experimental).RefreshModuleProvidersCommandId(); ok {
	moduleHooks = append(moduleHooks, callRefreshClientCommand(svc.server, commandId))
	}
	if commandId, ok := lsp.ExperimentalClientCapabilities(cc.Experimental).RefreshModuleCallsCommandId(); ok {
	moduleHooks = append(moduleHooks, callRefreshClientCommand(svc.server, commandId))
	}
	if commandId, ok := lsp.ExperimentalClientCapabilities(cc.Experimental).RefreshTerraformVersionCommandId(); ok {
	moduleHooks = append(moduleHooks, callRefreshClientCommand(svc.server, commandId))
	}
	if cc.Workspace.SemanticTokens != nil && cc.Workspace.SemanticTokens.RefreshSupport {
	moduleHooks = append(moduleHooks, refreshSemanticTokens(svc.server))
	}

We may need to add another hook which republishes relevant diagnostics.
