Update LUKSO networks

[JordyDutch]

Hello Team!

I've updated the data for both LUKSO Mainnet and Testnet.

Changes

• Updated the info for the LUKSO Mainnet and Testnet networks.
• Differentiated the icon for Testnet from Mainnet and updated the icons to the current ones.
• Updated RPC's
• We had a reusedChainId flag since we are using the ID that Kovan was using previously, but since Kovan got deprecated a long time ago I think it's time to remove this so that we can show up in the UI 🙏🏼

You successfully submitted a PR! Due to the amount of PRs coming in: we will only look at PRs that the CI is happy with. We can also not hold your hand getting the CI green - just look how others that where merged did it and RTFM. So as long as there is any CI check that reports an error - no human will look at this. You might be able to ask for some support after supporting the project - e.g. by sending funds to lists.eth. When you fixed things after a requested change - then you also need to (re-)request a review.
