[BUG] package contains legacy information

[stockholmux]

Describe the bug

package.json contains legacy information.

• "homepage": "https://www.opensearch.co/products/kibana", - this URL will not exist.
• build points to a number and sha hash that are probably not valid any longer.

It's questionable to have the author field still pointing to someone not involved with the fork - I'll leave this call to someone else.

Thanks for reporting the issue, i we'll get the listed two item fixed but again we need to figure out the last one on author name.

@stockholmux I've updated both information #238
