This is currently needed because a source file is generated with the package version number.

The usage is in cucumber-js when we generate the meta message: https://github.com/cucumber/cucumber-js/blob/6eede88fe6e6aed83a1ac581740d179e09643e3b/src/cli/helpers.ts#L105

I don't think we should need this - I'll see if I can get the version by interrogating the package.json instead (which is what people normally do).
