feat(owothia): Remove stopwords r/1275

Remove a (currently rather brief) list of stopwords from the verbs
considered for owo'ing. The specific case I wanted to remove here is the
verb "'s" from a contraction (there have been a fair number of "'s me
owo") but I've added a few more just for good measure.
