bugfix ~ (package) work-around for npm publish bug (see GH:npm/cli#…

…6137)

## [why]

Using the text "require('fs').writeFileSync(...)" blocks `npm publish` from completing
successfully; it faults with a horribly vague `npm ERR! code E403 ...` error. Minor
modification of the text will bypass the fault.

Issue raised at [GH:npm/cli#6137](npm/cli#6137).
