Feedback for “Techniques | Graph prompting”

In the `Techniques | Graph prompting` page the referenced [GraphPrompt (Liu et al. 2023)](https://arxiv.org/pdf/2302.08043.pdf) is unrelated to language models and LLM prompting. It's about pre-training graph neural networks and learning task-specific "prompt" vectors for downstream tasks.
Maybe this page should be removed to avoid confusion for new readers?

Open the `Techniques | Graph prompting` page and review its reference to GraphPrompt (Liu et al. 2023), then compare it with the linked paper. Confirm whether the page should be removed to prevent confusion; done means the documentation no longer presents this unrelated work as language-model prompting.
