Outdated link to ndjson.org

[AGrzes]

The documentation is linking to https://ndjson.org that expired and now is serving some suspicious content.

It should probably be replaced either with link to github

Migration to jsonlines may be an option, but it would need more than simple documentation update:

• Confirming that pnpm conforms to jsonlines spec
• Changing name of switch option
