@aleksander-dytko I've set this to Blocked on the DevEx board until Connectors delivers camunda/connectors#2896.

@aleksander-dytko we have a blocker here with Connectors, but do you want me to split this PR and just include the non-Connectors references? How quickly do you want me to remove these?

[akeller]

@aleksander-dytko I've removed Connectors from the scope of this PR, but do you have a recommendation for what I should do with the Tasklist API tutorial?

Do you want this PR to ship this week? If so, I will do the brute force method and delete remaining references and put at clean up issue into the DevEx backlog. See quick feedback poll here.

There is one one SM reference to the community spring-zeebe project re: connectors as well. I'm not sure if you'd like the attention label on that, too, or to add it to the Connectors ticket so it doesn't get lost, but otherwise good to go from me. 👍

Can you add it to the Connectors ticket? @conceptualshark

After a DM with @aleksander-dytko yesterday, I'm merging this.
