Missing feature_not_enabled error code

[ellnix]

Got this error trying to use vector store:

     MeiliSearch::ApiError:
       400 Bad Request - Passing `embedders` in settings requires enabling the `vector store` experimental feature. See https://github.com/meilisearch
/product/discussions/677. See https://docs.meilisearch.com/errors#feature_not_enabled.

There is no feature_not_enabled heading on https://docs.meilisearch.com/errors#feature_not_enabled

As a reminder: when fixing this, review error heading levels. Off scope, but it's a small fix

[ellnix]

Do you mean that all errors should have a level 2 heading? I can't really see any logic to the level 3 headings as it stands.

[ellnix]

I wasn't sure what you meant regarding the headings, I'll wait for clarification on that.

If you'd rather take care of this yourself, feel free to close the PR, no hard feelings.

[guimachiavelli]

Oh, sorry, that was a reminder for myself, quickly jotted down during a meeting. Apologies for the confusion, please ignore that comment.

[ellnix]

Ah, no problem. That makes a lot more sense, I should have realized it was a note to self in retrospect.
