DEPRECATED: Upgrade to runtime v1.19.1

SubSquare has made some updates to a program called Kintsugi. Here are the changes:

• They updated some important parts of the program to make it work better.
• They made it so that people can vote and make decisions faster.
• If you want more details about the changes, you can look at these websites:

  • https://github.com/paritytech/polkadot/releases/tag/v0.9.29
• If you want to use this new version, you need to use a client called v1.17.4.
• This update won't break anything, so everything should still work the way it did before.
