codegen doesn't find the library

Description

I'm updating @react-native-vector-icons/common to be in line with the latest create-react-native-libarary. I modified the codegenConfig in my package.json and the package was no longer being discovered when I run "react-native codegen"

The code that does this ignores errors in a libraries project.json. The error was

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './package.json' is not defined by "exports" in /home/johnf/work/inodes/react-native-vector-icons/node_modules/@react-native-vector-icons/common/package.json

I fixed this by adding the following to package.json

diff --git a/packages/common/package.json b/packages/common/package.json
index fc67253..20ec4aa 100644
--- a/packages/common/package.json
