The current error message "This mutates a global or a variable after it
was passed to React" no longer makes sense since we now have more
specific error messages for different kinds of Effect.Mutate or
Effect.Stores. This replaces the fallthrough "Other" case with a
more generic message. It's not perfect, but it's a little more accurate
than what is currently emitted
The proper fix might be to treat functions as mutable objects and allow
the mutation, or special case `Function.displayName`. For now though
this PR just updates the message in the meantime so it's less
confusing.
