bindings-javascript : remove package.json from git (#4001)

This commit removes package.json from git and adds package.json to the
gitignore.

This file is generated by CMake configure and will be updated and
overwritten causing a lot of noise in the git history.
It have also been updated manually as part of our release process which
will not be needed either.
