docs: integrations W&B update (#28059)

Issue: Here is an ambiguity about W&B integrations. There are two
existing provider pages.
Fix: Added the "root" W&B provider page. Added there the references to
the documentation in the W&B site. Cleaned up formats in existing pages.
Added one more integration reference.

+# Weights & Biases
+
+>[Weights & Biases](https://wandb.ai/) is provider of the AI developer platform to train and 
+> fine-tune AI models and develop AI applications.
+ 
+`Weights & Biase` products can be used to log metrics and artifacts during training, 
+and to trace the execution of your code.
+
+There are several main ways to use `Weights & Biases` products within LangChain:
+- with `wandb_tracing_enabled`
+- with `Weave` lightweight toolkit
+- with `WandbCallbackHandler` (deprecated)
+
+
+## wandb_tracing_enabled
+
+See a [usage example](/docs/integrations/providers/wandb_tracing).
+
+See in the [W&B documentation](https://docs.wandb.ai/guides/integrations/langchain).
+
+```python
+from langchain_community.callbacks import wandb_tracing_enabled
+```
+
+## Weave
+
+See in the [W&B documentation](https://weave-docs.wandb.ai/guides/integrations/langchain).
+
+
+## WandbCallbackHandler
+
+**Note:** the `WandbCallbackHandler` is being deprecated in favour of the `wandb_tracing_enabled`.
+
+See a [usage example](/docs/integrations/providers/wandb_tracking).
+
+See in the [W&B documentation](https://docs.wandb.ai/guides/integrations/langchain).
+
+```python
+from langchain_community.callbacks import WandbCallbackHandler
+```
