Revert inclusion of ci skip in release commit msg

This reverts PR #1423 which added the ci skip text into the default
release commit.  This broke many developers workflows because it pushes
a choice about CI/CD process into default configuration.  If developers
genuinely want to skip CI/CD for the release commit then they already
had configuration to override the commit message and inject the
necessary ci skip text.  However, the maven-release-plugin itself should
not make any assumptions about developers CI/CD setups, nor do anything
by default that might cause those to skip release commit builds that
developers might be relying upon.
