This is one of some potential PRs to be raised, to fix various spellings mistakes.

They are split because otherwise the change would be huge and difficult to review.

On the other hand, the latest Visual Studio Code automatically formats the code a little different, by putting some spaces here and their, I hope it doesn't bother in future PRs, specially I see we have "Run Prettier on codebase" in the PR checks.

Also, is ok if multiple commits are created, one for each 'word', and the PR is squashed later? What are your preferences?

Thanks for your contribution! It would be better to do like this PR and include multiple typo fix in the same commit.
However it would be nice if you could open a different PR for the documentation / code
