[monorepo-scripts] Format changelog dates as UTC timezone +0:00

[dekz]

Description

Down under is in the future and causes many conflicts when formatting the timestamp in the local context. All previous releases jumped a day ahead. By setting this to UTC we will have consistent formatted dates in the changelogs no matter where one publishes from.

npm-cli-login fails on node 10 as a deprecation in node 9 has finished. This package appears to be unmaintained so we now have a fork with a fix
