feat: Flag easy-to-fix typos in set phrases that pass spellcheck

[hippietrail]

I propose having one lint that covers all the easy cases of making a typo within a common phrase where each word is still a legitimate dictionary word.

Anything that requires additional heuristics or a typo in a single word that results in another dictionary word don't belong here. I'll try to think of examples of those to add here. The former probably warrant a lint each of their own.

Examples of ones that do belong here:

• trail and error → trial and error

My browser can detect the first one:

Examples that don't belong here:

• I though of an example → I thought of an example (single word, requires more logic to catch varied cases)
• underling → underlying (single word, so would require heuristics)

This is what was covered in #550. I'll add more cases in #589
