Deprecation warning when returning within an ActiveRecord transaction in Rails 6.1

[cheeseweasel]

We're getting the following deprecation warning from acts_as_votable in Rails 6.1:

DEPRECATION WARNING: Using `return`, `break` or `throw` to exit a transaction block is
deprecated without replacement. If the `throw` came from
`Timeout.timeout(duration)`, pass an exception class as a second
argument so it doesn't use `throw` to abort its block. This results
in the transaction being committed, but in the next release of Rails
it will rollback.
