Update pipeline tag and add project page link

This PR improves the model card by:
- Updating the `pipeline_tag` from `text2text-generation` to `text-generation`, aligning with the specified pipeline for this model on the Hugging Face Hub.
- Adding a direct link to the project page (https://itay1itzhak.github.io/planted-in-pretraining) for easier access to more information about the research.

 # Model Card for T5-Flan
@@ -23,12 +23,13 @@ This 🤗 Transformers model was finetuned using LoRA adapters for the arXiv pap
 We study whether cognitive biases in LLMs emerge from pretraining, instruction tuning, or training randomness.
 This is one of 3 identical versions trained with different random seeds.

 ## Evaluation
 
-- Evaluated on 32 cognitive biases from Itzhak et al. (2024) and Malberg et al. (2024)
-- Metrics: mean bias score, PCA clustering, MMLU accuracy
-- Findings: Biases primarily originate in pretraining; randomness introduces moderate variation
