Notes

• CLA signed
• ❓I'm not sure if only (docs/reference/api/README.md) or also (docs/reference/api.md) need to be edited. I got the feeling that docs/reference/api.md might be stale, but edited it anyway

Hi @MichaelHirn. Thanks for your PR.

I'm waiting for a feast-dev member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

@MichaelHirn you should probably backport this to the 0.7 branch as well, because that is what is going to be live on docs.feast.dev
