[D&D Character] fix typos in approaches

[colinleach]

As you said:

So we'll see all the typos shortly....

This is the first tranche. There seems to be something cursed about setattr.

Where I removed the bit that says (_as is the variant below_) on the last line of that document, I wondered if the whole paragraph is repeated needlessly? Line 78 duplicates line 41.

Yes - it is repetitive, but I thought I'd keep the pattern of fully describing each code block. I know for that last one the "big idea" is where to put the ability tuple ... but decided that duplicating the sentence wasn't the end of the world.

Conversely, if you'd like to change the code example to use one of the other non-static method variants, we can then talk about how it follows one of the other approaches. 😄

I really wouldn't like to do this!

No worries about the repetition. The main point stands: we couldn't have "the variant below" as the last words in the document, where there's no "below".
