Upgrade to Cosmos SDK v0.50

[johnletey]

Now that the v1.0.0 release tag has been cut, the Noble team will start working on upgrading the module to the latest stable release of the Cosmos SDK. Below, you can find a list of tasks we will complete and open PRs for!

• Update module path to include a v2 suffix. This is to follow standard go versioning best practices.
  • chore: update module path to v2 #3
• Update Protobuf definitions to be compatible with Cosmos SDK v0.50, utilizing their builder.
  • feat: upgrade protobuf to cosmos sdk v0.50 #4
• Bump Cosmos SDK and CometBFT to the latest patch release of v0.50.x, ensuring builds and tests still work.
  • feat: upgrade module to cosmos sdk v0.50 #5
• Support App Wiring to be compatible with the latest Noble codebase.
  • feat: support app wiring #6
  • We have decided against supporting AutoCLI in this upgrade as we have multiple custom query commands, and AutoCLI doesn't support maps currently. Support can be added at a later time via a quality of life upgrade.
• Reorganize repository structure to align with Noble's standard.
  • chore: reorganize repo structure #7
• Utilize collections for managing state, simplifying and removing a lot of boilerplate code. @spoo-bar
  • refactor: use collections API for state management #10

Any other items will be added adhoc to this list as they come up!
