fix(docs): update broken links to getting-started pages

[JoschuaSchneider]

Description

The links in the getting-started/whats-new section of the beta docs are all prefixed with /docs causing them to 404.

I removed the /docs prefix as it is not configured that way in the starlight config.

This is great, thanks @JoschuaSchneider!

Sorry for the noise, trying to see if I can fix that failing CI step for examples
