Summary of changes:

Updated docs/gdevelop5/tutorials/how-to-use-gdevelop-as-a-team/index.md to document the toolbarButtons section in gdevelop-settings.yaml, including the new hook field that lets buttons run npm scripts automatically at editor lifecycle events (onEditorReady, onPreviewStart, onPreviewEnd). The variable string default value fix is a bug-fix that corrects the runtime to match documented behavior, so no docs change was needed there.

Please review the changes carefully before merging.
