This pull request includes significant updates to dependencies, refactoring of the main application setup, and removal of several plugins. The most important changes involve updating dependencies in package.json, refactoring src/app.js to use the latest probot setup, and removing multiple plugins that are no longer needed.

Note: I couldn't figure out how to run the bot locally to ensure it will start.
