Serializable interface deprecated

[PAXANDDOS]

2023-02-13T14:57:52+00:00 [info] Deprecated: Resque\Helpers\SerializableClosure implements the Serializable interface, which is deprecated. Implement __serialize() and __unserialize() instead (or in addition, if support for old PHP versions is necessary)

_{BTW my PR is in the progress, adding this issue just to keep track}
