style(docs): Trim trailing whitespace in HTML docs
Many editors remove these automatically anyway which makes opening and editng the docs cause a bunch of noise. This is just to get the noise out of the way in a style commit so it doesn't leak into other PRs

The API design had two goals in mind. First, users

Second, the simplicity and the feel of the Lua language should be
