Pokey "return from leave" discussion list

[phillco]

Pokey needs to do:

• Bump tree-sitter-kotlin vscode-parse-tree#88

Discussion:

• Flatten scope type list #2628, "Basically I didn't want to touch our csv parser without first talking to pokey since a lot of these list and spoken forms are used in places like the cheat sheet and the tutorial."
• Don't use file system for custom spoken form tests #2638 Is this still worth doing even if it doesn't affect test reliability?
• Added the ability to remove whitespaces with join token #2651 - do we want to improve how this would handle multiple separate targets? Is that even desirable?
