fixed stuff and upgrade all deps

[zamrokk]

Setting up code from unmaintained repository to trilitech repo and later, updating the documentation to point to it

I migrated all dapp-x trainings

It would be helpful to have a README in each folder with installation steps and a link to the tutorial instructions, like in this file:
https://github.com/trilitech/tutorial-applications/blob/main/bank-tutorial/README.md

I don't know enough about taqueria to be able to clone and run this project easily, so it would be good to tell people to make sure taqueria and other prereqs are installed and then clone the repo and set up taqueria with an account.

@timothymcmackin README are part of docs.tezos.docs (https://docs.tezos.com/tutorials/dapp)
It is a real pain to duplicate tutorial instructions on both side :/

Prerequisites are here : https://docs.tezos.com/tutorials/dapp#prerequisites (the other PR is not merged, please take the right versions of the documentation if you want to rerun the tutorial)

I always refer to a supported taqueria and other dependency versions

How about at least a README with a link to https://docs.tezos.com/tutorials/dapp?
