Revert "build(deps): bump next in /recipes-app/iot2050-conf-webui/files"

This reverts commit e64ba7f.

This change needs to be reversed because our Debian version does not
satisfy the minimum version requirement for Node.js regarding package
locking. Our project does not utilize the function associated with this
vulnerability, so it should not pose an issue for us.
