Suggestion: Replace polkadot-launch with Zombienet or parachain-launch

See below for motivation:

• https://github.com/paritytech/polkadot-launch/issues/189#issue-1261901795

I tried to use parachain-launch.

There are some images here: https://hub.docker.com/u/uniquenetwork

Maybe I can use this image? https://hub.docker.com/r/uniquenetwork/quartz-node-public

Reviving this issue with news that we're deploying Zombienet in our CI very soon! It's been possible to use Zombienet natively or with the images you correctly pointed to,

https://hub.docker.com/r/uniquenetwork/quartz-node-public for a Quartz node

and

https://hub.docker.com/r/uniquenetwork/unique-node-public for a Unique node.

But with this PR, test network specs will appear in the root of the repository (and a whole script in tests to launch it), which will hopefully make it easier to get started.

We have updated our test infrastructure to use our own parachain launcher: https://github.com/uniquenetwork/baedeker, which has better integration with https://github.com/uniquenetwork/chainql, which we were using for some tasks (I.e chopstics-like parachain fork tests: https://github.com/UniqueNetwork/unique-chain/blob/master/.baedeker/forkless-data.jsonnet).
