[Bug]: Update or Remove Integrations page

[aaltay]

What happened?

The page is only linking to kettle and that was replaced with apache hop. We should update the page or remove the page.

There are also missing integrations for:

• TFX: https://www.tensorflow.org/tfx
• Temporian: https://temporian.readthedocs.io/en/latest/
• Scio: https://spotify.github.io/scio/
• Klio: https://github.com/spotify/klio
