Remove Babel

[hyperupcall]

Description

Fixes #1098

As mentioned in #1098, this removes Babel. It wasn't being used (see linked PR for details). This simply removes the Babel dependencies, configuration, and references to it from comments. As a side-effect, removing Babel will prevent errors such as the following from being printed on install:

I'm leaving a comment here to note the OED developer info at https://openenergydashboard.github.io/developer/technologies.html still shows babel being used. It needs to be updated along with a number of pages based on changes in our core technologies. This is no reflection on the PR and simply to leave a record.
