use-pronow defaults totrue. The action will use thelocalstack/localstack-proimage by default. Workflows that relied on the community image without settinguse-prowill now get the Pro image, which requires aLOCALSTACK_AUTH_TOKEN. Setuse-pro: 'false'explicitly if you need the community image. For newer versions of LocalStack these images are equivalent.
use-proinput will be removed in a future release as we are consolidating our docker images.
