Wrong Hugging Face link for Spider dataset in bigcode-evaluation-harness/docs/README.md line 434

[354246695]

Hi maintainers,

Line 434 of bigcode-evaluation-harness/docs/README.md currently links to
https://huggingface.co/datasets/spider when describing “Spider for SQL code generation”.
The canonical Spider dataset on HF is actually hosted at
https://huggingface.co/datasets/xlangai/spider.

Could you update the hyperlink so readers land on the correct page?
(The wrong one has a nice avatar, but no data files 😄)

Thanks for the great work!
