Invalid hyperlink error 404 in optimum export Doc

Hi,

There is a small issue in optimum export Doc.

Link to doc page: https://huggingface.co/docs/optimum/exporters/onnx/usage_guides/export_a_model#selecting-a-task

The link for here was invalid

First, you can check the list of supported tasks for both PyTorch and TensorFlow here.

Is the correct link supposed to be as follows? https://huggingface.co/docs/optimum/exporters/task_manager#task-names

If yes, I can submit a PR to fix it.
