LPD-69094 docker-database-saas.gradle: uses --simplify-by-decoration for the strictest history of a given file

A chat with AI revealed that the combination of the file path pathspec
and the --simplify-by-decoration results in the strictest possible history
filtering for a particular file path.

All of the following flags were tried, and were not sufficient (they
still printed commits that had close matches, but the exact file path
did not exist at that path for that commit):

--find-renames=100%
--full-history
--no-renames
--diff-filter=AM

The following command was used as a test:

git show <commit_hash>:<file_path>
