Which canary version will you have in your reproduction?

turbo@2.3.4-canary.2

Enviroment information

CLI:
   Version: 2.3.4-canary.2
   Daemon status: Running
   Package manager: yarn

Platform:
   Architecture: aarch64
   Operating system: macos
   WSL: false
   Available memory (MB): 7456
   Available CPU cores: 11

Expected behavior

In the reproduction, I've edited the starter so the web package has an additional verify script. This task depends on web:build. When running turbo verify I would expect web:build and web:verify to run.

Actual behavior

web:build, docs:build and web:verify are run despite docs:build not being necessary

To Reproduce

Run turbo verify in the reproduction project
