fix(db-mongodb): updateOne mutates the data object and does not transform it for read (#13065)

Fixes https://github.com/payloadcms/payload/issues/13045

`updateOne` when returning is `false` mutates the data object for write
operations on the DB, but that causes an issue when using that data
object later on since all of the id's are mutated to objectIDs and never
transformed back into read id's.

This fix ensures that the transform happens even when the result is not
returned.
