Full changelog

Fix dagger release publishing to bust cache of operations that involve external state by @tiborvass + @sipsma in https://github.com/dagger/dagger/pull/13279
The previous v0.21.1 release hit a long-standing bug in our version module tooling where certain operations did not bust cache based on changes in external state. We hit this for the first time because v0.21.0 and our infrastructure have had significant improvements in cache re-use.
