Update Next.js version and remove GridList component

The Next.js version was updated in the 'pnpm-lock.yaml' file which resulted in changes to multiple dependencies. Also, the '_components/grid-list.tsx' file was deleted as it was deemed no longer necessary. Additional small changes were made to the blog page and 'marketing.json' file.
