While testing the sdk I have noticed the examples are using old github headers ``` github-public-key-signature github-public-key-identifier ``` instead of ``` x-github-public-key-signature x-github-public-key-identifier ``` as announced [here](https://github.blog/changelog/2025-01-17-updated-headers-for-github-copilot-extension-requests/). I raised a small PR to fix it: #129
