Change deprecated polkadot-launch library for parachain-launch

[dudo50]

My suggestion:

Replace startup guide which uses deprecated library polkadot-launch for one that is maintained. For example parachain-launch.

Thanks for consideration

There are 2 projects to consider: parachain-launch and zombienet.

Any updates on this? Would be very useful if we get some parachain-launch or zombienet configs for Basilisk

Deprecated for chopsticks? (can reopen if still wanted)
