Found a small wording change compared to the codebase, the rest looks fine

Since this is the last bigger docs PR for error codes, I did a check docs towards the codebase:

These are used in the codebase and needs documentation

• 08N19
• 08N20
• 08N21
• 22004
• 22012
• 42N0A
• 42N3A
• 42N3B
• 42N3C
• 50N18
• 50N19
• 50N20
• 52N21

Apart from the ones above, we have some which are present in the codebase but unused. Before adding the internal procedure for docs testing we need to decide whether these should be cleaned up from codebase or documented. For those that are standard defined I think it is better to clean up as it is only a subset, users cannot get them right now and they are already defined in GQL standard. But I am not 100% sure about the Neo4j defined unused ones, for these we need to be careful so not codes are re-used

Looks good! We also need to document the ones listed in the bigger message. But feel free to make a Trello card/separate PR for that

Thanks for the documentation updates.

The preview documentation has now been torn down - reopening this PR will republish it.

Thank you, @Lojjs! I'll follow your advice 🙂 and open a new PR for those errors
