Subject: [PATCH] Handle non-string partial body in
 ActionView::CollectionCaching

Followup: https://github.com/rails/rails/pull/48645

Some template engines such as `jbuilder` use these Action View primitives
with types other than strings, which breaks a bunch of assumptions.

I wish I could add a test for this, but this is deep in private methods
I don't see a way to cover this.
