How to resolve this issue?
After the wait time has elapsed, a review can be triggered using the `@coderabbitai review` command as a PR comment. Alternatively, push new commits to this PR. We recommend that you space out your commits to avoid hitting the rate limit.How do rate limits work?
CodeRabbit enforces hourly rate limits for each developer per organization. Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout. Please see our [FAQ](https://coderabbit.ai/docs/faq) for further information.Commits

Walkthrough
The changes introduced a new Container type in the Simple Serialize (SSZ) library and enriched the BaseSSZType interface with a ChunkCount method. This Container supports essential SSZ functionalities, including size calculation, fixed size check, element handling, and hash tree root computation. The withdrawal handling now integrates with this enhanced SSZ structure, and new tests ensure the consistency and accuracy of hash tree root calculations.
Changes
| Files | Change Summary |
|---|---|
| mod/primitives/pkg/ssz/container.go | Added Container type with methods for SSZ operations, including sizes, type, elements, and hash calculations. |
| mod/primitives/pkg/ssz/types/types.go | Extended BaseSSZType interface to include a new ChunkCount method for chunk handling. |
| mod/engine-primitives/pkg/engine-primitives/withdrawal.go | Introduced ChunkCount method in Withdrawal struct to return chunk count. |
| mod/engine-primitives/pkg/engine-primitives/withdrawal_test.go | Added test to compare hash tree roots computed by built-in method and custom container. |

In the code, new lines do unfurl,
SSZ containers now in a whirl,
Chunks and roots with hash in sight,
Structs now handle them just right.
Tests ensure our data's grace,
As algorithms set the pace.
🐇✨ Happy coding, in this space!

Early access features: enabled
We are currently testing the following features in early access: - **OpenAI `gpt-4o` model for code reviews and chat**: OpenAI claims that this model is better at understanding and generating code than the previous models. We seek your feedback over the next few weeks before making it generally available. Note: - You can enable or disable early access features from the CodeRabbit UI or by updating the CodeRabbit configuration file. - Please join our [Discord Community](https://discord.com/invite/GsXnASn26c) to provide feedback and report issues. - OSS projects are currently opted into early access features by default.
