Add Release notes for Open Data Hub 2.X

Hi,

There are missing release notes on the website for Open Data Hub 2.X:
https://opendatahub.io/docs/release-notes/

https://github.com/opendatahub-io/opendatahub.io/blob/main/src/content/docs/release-notes.md


Are there any plans to add them?

Thanks.
