2.x fix build and deploy

[tenkoma]

Apply #7820 to 2.x branch.

Version 2.x document deployments are also broken, as is version 3.x. I will fix it.

When I created a fix for the 3.x branch, it was successfully deployed. 🎉 ~Therefore, this time, I will try to do the merge without review.~ Please review :)

~The build succeeded and is now merged.~
