/**
* This function ensures that the current working directory on Windows
* always has an uppercase drive letter (i.e., C: vs. c:).
*
* Why?
* 1. Different utils like "true-case-path", "normalize-path", "slash" treat Windows
* drive letter differently. "true-case-path" will uppercase, others usually don't care.
* As a result path normalization produces different results depending on current cwd (c: vs. C:)
* which manifests in weird bugs that are very hard to debug.
*
* We can't control community plugins or site code, so everything should be working
* even with a different set of libraries.
*
* Related: https://github.com/Profiscience/true-case-path/issues/3
*
* 2. Builds save some paths in a cache. If you run the first build from "c:" shell
* and then the next one from "C:" shell, you may get a bunch of webpack warnings
* because it expects module paths to be case-sensitive.
