[Bug]: Messages loss on restarts

[limitium]

Bug Description

Current implementation losses messages, because SolaceTask#commit() method in reality doesn't have guarantee that all messages from the previous poll() call committed. This is explicitly highlighted in kafka-connect-api 3.6.1

"This method is invoked periodically when offsets are committed for this source task. Note that the offsets being committed won't necessarily correspond to the latest offsets returned by this source task via poll()."

Expected Behavior

Ack only really committed messages

Steps to Reproduce

Problem scenario:

1. Connect calls poll() which returns, let's say 100 record
2. Connect calls commit(), after partial message publishing 30
   a. Current implementation acks all 100
3. Restart connect and 70 msgs will be lost
