Create map of groupId to CustomConnectionSpec when loading connections before displaying in the Resources view

[shouples]

Could be handled here with group-level ContainerTreeItem<DirectEnvironment>:

vscode/src/viewProviders/resources.ts

Lines 570 to 576 in a35be57

	export async function loadDirectResources(): Promise<DirectEnvironment[]> {
	// fetch all direct connections and their resources; each connection will be treated the same as a
	// CCloud environment (connection ID and environment ID are the same)
	const directEnvs = await getDirectResources();
	logger.debug(`got ${directEnvs.length} direct environment(s) from GQL query`);
	return directEnvs;
	}

After we make the GraphQL query, we can look up the stored connection (including formConnectionType and groupId):

• if there's a groupId, add to the map and then make a container for it to display
• if there's no groupId, display it on its own
