Drop display field

resolve: #180

I'm open to this being post-processed out when we are going from the file in this repo to the file in the npm package, but not for removing the display tag inside these json files.

Having _display in ensures that each base json file is fully self contained

Thank you for your review.

I changed code that drop display field when generating npm package.
Most of the codes are unusable, so I removed all commits and rebase latest main branch.

Does it accord that you think？
