Update Next.js configuration and package dependencies

- Modified redirects in next.config.ts to change the destination for "/sohbet" to "/listem".
- Added new dependencies in package.json: marked, motion, react-markdown, remark-breaks, remark-gfm, shiki, and use-stick-to-bottom.
- Updated pnpm-lock.yaml to reflect the new package versions and dependencies.
- Removed obsolete stack files for Flutter, Nuxt, Nuxt.js, React Native, and Svelte from the UI/UX Pro Max skill data.
