scripts: add origin commit identification based on specific patterns

Browse Source 
This patch adds the functionability to smartly identify origin commit
of the translation by matching the following patterns in commit log:
1) update to commit HASH
2) Update the translation through commit HASH
If no such pattern is found, script will obey the original workflow.
