codespell works by having a dictionary of pairs of malformed words and
their correct equivalents. This means that codespell will not catch most
issues out of the box, but we can train it based on the common spelling
issues we encounter along the way.
The plan is to add a pair to `dictionary` every time we encounter a typo
during a code review, and we ensure that error will not happen again
anymore.
