fs-extra/readJsonSync breaks comments in tsconfig.json

[rob3c]

TypeScript has allowed comments in tsconfig.json files for almost a year now (see microsoft/TypeScript#4987), but the current use of readJsonSync() in fs-extra to parse tsconfig.json files doesn't seem to like them.

Maybe switching to a tsconfig-aware library like https://github.com/TypeStrong/tsconfig would better support the full format?

Good call, I'll look into it, thanks!

PR welcome here. Otherwise this is off our radar for now.

Thanks,
