[MSHARED-1202] update to parent POM 39

[elharo]

contains the usual automated spotless churn that this update requires.

check for duplicate license header:

git grep -c "Licensed to the Apache Software Foundation (ASF) under one" | grep -v ":1"

Good will be to have 2 commits - one with parent update and one with code reformat.
After merge we can add commit with reformat to .git-blame-ignore-revs

Thanks for the grep command. It found one duped license I had missed.

Please prepare 2 commits - one with change and one with code reformat

It all gets squashed in the end. Separating the commits for the update and the reformatting leaves broken states in the history.
