Prettify printed results in Tutorials

[tholor]

In most of our tutorials, we print the results of a pipeline at some point - mostly using pprint, print_answers or print_documents.
Sometimes the printed results are very verbose and it's hard to see the most relevant information that users are actually interested in.

Example:

In Tutorial 13 we print something verbose like this:

{'documents': [{'content': "Dry Cleaning are an English post-punk band who formed in South London in 2018.[3] The band is composed of vocalist Florence Shaw, guitarist Tom Dowse, bassist Lewis Maynard and drummer Nick Buxton. They are noted for their use of spoken word primarily in lieu of sung vocals, as well as their unconventional lyrics. Their musical stylings have been compared to Wire, Magazine and Joy Division.[4] The band released their debut single, 'Magic of Meghan' in 2019. Shaw wrote the song after going through a break-up and moving out of her former partner's apartment the same day that Meghan Markle and Prince Harry announced they were engaged.[5] This was followed by the release of two EPs that year: Sweet Princess in August and Boundary Road Snacks and Drinks in October. The band were included as part of the NME 100 of 2020,[6] as well as DIY magazine's Class of 2020.[7] The band signed to 4AD in late 2020 and shared a new single, 'Scratchcard Lanyard'.[8] In February 2021, the band shared details of their debut studio album, New Long Leg. They also shared the single 'Strong Feelings'.[9] The album, which was produced by John Parish, was released on 2 April 2021.[10]", 'content_type': 'text', 'score': 0.5312093733737563, 'meta': {}, 'embedding': None, 'id': '83bc102774fd126712d6b2e67195ec79'}],

And there are a couple of other tutorials with similar cases.
To some degree, this might be related to our recent refactoring of primitives (#1398 ) and pipeline outputs.

Let's check all tutorials and improve the prints. Couple of options:

• Adjust print_answers / print_documents utils
• Adjust the str representation of Document / Answer and utilize this in the tutorials
• Use a custom print to only show certain attributes like here
