Fix versioning being done in two places

there is a _versioninfo file and a version in the package.json . We should remove _versioninfo and everywhere it is referenced.

Start by comparing the version in package.json with _versioninfo, then search the repository for every reference to _versioninfo. Remove the file and its references while preserving the package.json version, and verify that the project’s existing build or release checks still pass.
