Fix typos found by codespell

While (un)parseable is debatable, (un)parsable appears to be the preferred spelling:

• The word is missing from online dictionaries (Oxford Learner's, Cambridge, Collins, Longman, Merriam-Webster).
• The Google Ngram Viewer shows unparsable is more common than unparseable, although the latter has been gaining ground in the 21st century.
• Rules for removing last vowel when adding "-able"?

"Unparseable" is an acceptable spelling to us, so please leave that word as-is.

Done.

I am always perplex when native English speakers drop rules I had put substantial efforts to learn as a non-native speaker, such as Drop the E.

I am always perplex when native English speakers drop rules I had put substantial efforts to learn as a non-native speaker, such as Drop the E.

It's because native speakers don't care as much as non-native speakers. 😅 This is why non-native speakers often have more formal, correct grammar.

In this case, I'm trying to minimize churn on the code when either option works, regardless of popularity.

Thanks!
