fix(db-mongodb): properly sanitize updateVersion read result (#11589)

Previously, `db.updateVersion` had a mistake with using `transform({
operation: 'write' })` instead of `transform({ operation: 'read' })`
which led to improper DB data sanitization (like ObjectID -> string,
Date -> string) when calling `payload.update` with `autosave: true` when
some other autosave draft already exists. This fixes
https://github.com/payloadcms/payload/issues/11542 additionally for this
case.
