Fix e2e environment and smoketests

[alistair-singh]

All these fixes were made from clean build of nix environment and a clean checkout.

For some reason the polkadot-js-api does not obey the --nonce -1 flag anymore so I needed to remove it so that the testnet starts up correctly.

Tests Fixes:

• register_token
• send_token
• transfer_token
• set_price_params
• set_token_transfer_fees
• send_token_to_penpal

This is required to build lodestar. Python version 3.12 deprecates some required packages.

@alistair-singh I can't reproduce the issue on my laptop with your branch, --nonce -1 does work and the testnet starts up as expected.

Btw: for local test I would suggest to use a short epoch length with Snowfork/polkadot-sdk#170 included and I made another PR in #1274 based on yours.

Ok I will revert my changes to the nonce.
