feat(core): Deprecate the Hub constructor

MIGRATION.md

@@ -289,6 +289,45 @@ If you are using the `Hub` right now, see the following table on how to migrate

+The `Hub` constructor is also deprecated and will be removed in the next major version. If you are creating Hubs for
+multi-client use like so:
+
+```ts
+// OLD
+const hub = new Hub();
+hub.bindClient(client);
+makeMain(hub);
+```
+
+instead initialize the client as follows:
+
+```ts
+// NEW
+Sentry.withIsolationScope(() => {
+  Sentry.setCurrentClient(client);
+  client.init();
+});
+```
+
+If you are using the Hub to capture events like so:
+
+```ts
+// OLD
+const client = new Client();
+const hub = new Hub(client);
+hub.captureException();
+```
+
+instead capture isolated events as follows:
+
+```ts
+// NEW
+const client = new Client();
+const scope = new Scope();
+scope.setClient(client);
+scope.captureException();
+```
+
 ## Deprecate `client.setupIntegrations()`
 
 Instead, use the new `client.init()` method. You should probably not use this directly and instead use `Sentry.init()`,
