fix: allow the transitive phrasal verb "built in"

"built in" should not be unconditionally substituted by "built-in".
"Built in" is the valid past principle form of the transitive phrasal
verb "to build in", as
[seen](https://www.oed.com/dictionary/build_v?tab=phrasal_verbs#1351285480)
in the Oxford English Dictionary.
