[feature][tf/pt] integrate from_hub for all tasks

[felixdittrich92]

This PR:

• follow up on @fg-mindee from_hub for all tasks (TF and PT)
• fixes classification archs for push to hub which was not on track

TODO:

• upload dummy models to hub for all working models (exclude other ftm in tests)
• test for each uploaded model
• test whole workflow (push to hub / load from hub)

Documentation will follow in another PR (maybe same after datasets PR merge which needs also documentation)
