Subject: [PATCH] feat: adapter-vercel should generate sourcemaps (#5197)

* feat: enable sourcemap support

The adapter-vercel package were not generating sourcemaps. Therefore, it was impossible to correctly use any bug tracking tool.

* fix: add missing changeset

* style: fix README.md indentation

* fix: always generate linked sourcemaps and delete configuration option
