[DPE-5047] Update snap to 2.14.0-ubuntu1 with ML Commons fix

This PR backports upstream fix for ML Commons: opensearch-project/ml-commons#2675

To be added to our distribution.

Given we are currently targeting upstream branch 2.14, instead of upstream tag 2.14.0.0, this build is using a new release from our build from source: 2.14.0-ubuntu1.
