Get Github Actions for CodeClimate to support both LCOV and Simplecov at the same time

[corsonknowles]

CodeClimate is a utility that includes features for storing and viewing code coverage reports, as well as a browser extension to overlay code coverage results directly on Github pages in a repo.

CodeClimate uses Simplecov under the hood to support Ruby coverage.
It supports multiple JS coverage tools, in this case we are using LCOV.

We want to configure Codeclimate to upload an lcov Javascript test coverage report and include it alongside the existing covered Ruby report.

Our initial implementation with GitHub actions hits a broken promise error -- even when it finds the lcov file, it doesn't seem to be able to parse it properly.

You can see the upload failures here:
