Extend Auto-instr. of Vercel Crons

### Problem Statement

For NextJS there is a [Sentry config option ](https://docs.sentry.io/platforms/javascript/guides/nextjs/crons/#automatic-check-ins-vercel-only)`automaticVercelMonitors ` to automatically configure Check-in for Vercel Crons. However this functionality in Vercel is not limited to NextJS and could be extended to other platforms

### Solution Brainstorm

Extend this functionality to all platforms which are supported by Vercel Crons and Sentry. Today it is in `next.config.js` so it should at least be agnostic in Webpack, but ideally all plugins, and CLI if possible.
