Fix aliasing regression in post install script

[BSFishy]

Description

Previously, in 9abf87e, there was an aliasing regression in scripts/postinstall.js. Essentially it didn't rename files to their EUI counterpart. This PR fixes that and prepares OUI for the 1.1 release

Plugged the current version into Dashboards, ran yarn test:jest and yarn test:jest_integration and some errors popped up about these files not being found. Tested by publishing the fixed version to personal NPM account and testing the same thing with that version

Cool. For what it's worth, you should be able to directly test against OUI main by just setting the dependency in dashboards to point to the OUI git repo, which may be a little quicker.
