I'm not sure you're supposed to commit the build/ folder.

The content that you check into your git repository is completely up to you. If you dont need the content of build of devtool extension to be in the code, then make sure that the extenstion web app is always built and included in extension/devtools/build/ when you publish the package
As per docs,

What if I don't want the extension/devtools/build/ contents checked into source control?
As a package author, the content that you check into your git repository is completely up to you. If you want the contents of extension/devtools/build/ to be git ignored, then you'll just need to ensure that the extension web app is always built and included in extension/devtools/build/ when you publish your package. To do so, add the following to a .pubignore file in the extension/devtools/ directory:

!build
This will ensure that, even if the extension/devtools/build directory has been been git ignored, the directory will still be included when publishing the package on pub
