Fix: UpSampling2D bilinear channels_first bug

[tristandb8]

The current approach transforms the tensor to channels_last, before passing it in ops.image.resize, which has been defined as channels_first. This creates a bug, a passed in tensor [16, 3, 224, 224] will return as shape [16, 448, 224, 448] instead of [16, 3, 448, 448]. Setting the data_format as the expected channels_last fixes that issue.
Closes #21401

There was an issue with CLA, the author email it was asking me to verify doesn't exist. I made a new PR (#21456) instead, which passes the CLA and includes the required unit tests.
