Add noise interpolation and text intertpolation scripts to examples

[patrickvonplaten]

Noise and text embedding interpolation scripts like @karpathy's stable-diffusion-walk are very nice to make artistic designs / videos and are relatively easy to add. We could add them under https://github.com/huggingface/diffusers/tree/main/examples to make it more available to the community

Hi @patrickvonplaten, I've been working and modifying a copy of this script every day for the past 3 weeks. I would be happy to help add it! would you like a colab notebook with added video creation from generated frames? "Dream Seam" or as the exact .py file from karpathy's repo?

Very cool! Should we make it a community notebook (and add it under https://github.com/huggingface/diffusers/tree/main/examples/community - it'd be the first one 🥳 )

[danielpatrickhug]

Sure! I'll make a pull request to add the notebook to the community folder. The notebook is completely self-contained and should operate on the free version of google Colab - I've only tested it twice on the free version. I'll do my best to keep it up to date as the diffusers library updates.
