Update minimum maven version to match current stable version (3.6.3 -> 3.9)
According to https://maven.apache.org/docs/history.html:
Maven 3.6.3 and before has now reached its end of life and is no longer supported in any way.
This PR updates the version to current stable version 3.9.11
😄 even of ASF we need do some of updates https://issues.apache.org/jira/browse/INFRA-27147
This may conflict with our plans to move from 3.6.3 to 3.8 as minimum Maven version in CIs
