feat: support CJS configs in ES packages

[quisido]

Problem statement

When writing an application with "type": "module" in package.json, it becomes impossible to set the NYC config with JS, since it only supports the .js extension and it only supports CommonJS. As a result, any configuration in nyc.config.js will fail for trying to require an ES module.

This PR adds support for nyc.config.cjs, allowing packages with "type": "module" to still configure a nyc.config.cjs file for a CommonJS configuration.

Hi @CharlesStover , sorry for the VERY slow response! This PR must have gotten lost in the shuffle. We have since implemented a more robust triage process to make sure issues do not sit like that going forward. I will have the team discuss this PR and see how we would like to proceed.

This seems fine - it looks like you've followed the existing pattern, so I don't see any blocker on merging this.

[lmiller1990]

I'd generally like to see a test, but we haven't got any of the other permutations - I'm not sure how much work it would be to add some tests around the various module formats, but since this follows and existing pattern, I think we can merge this up as is. CI is green, so I'm reasonably confident. Let me find one more reviewer.

Hey @CharlesStover, just waiting on our infosec team to update the Snyk API key so the scan can run and we can ship this. I'm sorry for the delay.
