Update super_resolution.ipynb to resize the input tensor

[pjpratik]

The input tensor to the interpreter needs to be resized to take 1x50x50x3 image else it is throwing the dimension mismatch error.

Thanks.

@windmaple Can you take a look?

@pjpratik The test image is actually 50x50. Why do you need to resize it again? Unless you are using a diff test img?

Hi @windmaple

The example when run on colab with latest stable version TF 2.13 runs into an error. Please find this gist.

The converted tflite model has input shape of [1,1,1,3], and the setting the input shape via concrete function is not considered.

Thanks.
