Only running over "docs/" directory since it will likely have the
largest postivie impact and cause fewest issues.
Typos will do simple find-and-replace when it detects a word not in it's
dictionary. It does not have any regard for formatting based on
surrounding context. Care must be taken not no merge variable names in
same scope etc.
Typos can be driven by Github Actions:
