Improve the rollkit ignite app, to allow users with a running Cosmos SDK chain to migrate to rollkit.
Check out this guide for actual migration steps: https://github.com/rollkit/cosmos-sdk-starter/blob/main/sdk/docs/instructions/migration.md

Additionally, we should check if wiring the modules present on https://github.com/rollkit/cosmos-sdk-starter/blob/main/sdk wouldn't improve the UX for new users.

Tasks

• Bump rollkit to a specific version only (not always latest) (feat(rollkit): upgrade rollkit #192)
• Upgrade to rollkit v1 (feat(rollkit): upgrade rollkit #192)
• Wire modules from https://github.com/rollkit/go-abci-execution/tree/main/modules at ignite rollkit add
• Add ignite rollkit migrate-from-comet command (name tbd)
  • The default template should not scaffold migrations functions for existing chain. migrate-from-comet should scaffold and print instructions.
