### What does this PR do? It's common for monorepos to exclude portions of a large glob ```json "workspaces": [ "packages/**", "!packages/**/test/**", "!packages/**/template/**" ], ``` closes #4621 (note: patterns like `"packages/!(*-standalone)"` will need to be written `"!packages/*-standalone"`) ### How did you verify your code works? Manually tested https://github.com/opentiny/tiny-engine, and added a new workspace test. --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com>
