[Package development] error TS2307: Cannot find module '@bull-board/x' or its corresponding type declarations.

Hi I recently forked bull-board, looking into making package updates. When I checked out the repo and followed the instructions laid out in the README for developing on it, I got a typescript error when running yarn && yarn start:dev at the repo’s root directory:

yarn install v1.22.15
